The difference between isolated and insulated

2023-06-24 / / 0 Comments

Isolated and insulated both come from Latin insula, island.

The Latin word insulatus, made into an island, became isolato in Italian and both insulated and isolated in English.

The two English words have different meanings:

ISOLATED

Isolated means separated or set apart from others. You can be in a remote place without contact with anybody. Even with a lot of people around you at a party, you can feel isolated when you feel as if nobody notices you or makes contact with you.

You can also isolate something, identify,  for example, a problem, in order to deal with it.

And scientists can isolate a virus from an infected host.

INSULATED

Insulated is used to indicate that something is covered or wrapped in a material that protects from loss of heat, an electric shock, etc.

Without being isolated, children that grow up with overprotective parents may be insulated against and unprepared for the harsh realities of life.

If or whether?

2023-05-31 / / 0 Comments

If and whether are sometimes interchangeable but they 
have different uses.

You can use both if and whether in indirect questions:

She asked if I wanted tea or coffee.
She asked whether I wanted tea or coffee.

Whether is used in more formal contexts.

This is the main difference between if and whether:

IF

Use if where a condition is involved:

If it doesn’t rain tomorrow, we’ll play golf.
I’d be grateful if you could pick me up at the railway station.

WHETHER

Use whether in reference to alternatives or a choice:

We discussed whether we should walk or take a taxi.

Use whether before an infinitive:

I’ve been wondering whether to let him use the car again.

Use whether after a preposition:

They talked about whether it was a mistake.

A lone woman is sitting on a grassy beach by a large lake.
She debated with herself whether to take a swim or go for a walk

To understand the difference between if and whether, look at these two examples:

1. Let me know if you got his letter.

If you got his letter, tell me so, but only if you got it. You don’t have to tell me if you did not get his letter.

2. Let me know whether you got his letter.

No matter whether you got his letter or not, please tell me.

What’s the difference between different and various?

2023-04-24 / / 0 Comments

In my job as copyeditor I notice that writers tend to overuse different when they should write various instead.

Different, as you know, means that something is not the same as something else. One thing is different from another thing, or two or more things are different, not alike.

They have different models of sunglasses

Various implies that there is a variety among things; there are several different variants of something. Various is used before a plural noun about things that are of the same type but not all of exactly the same kind.

A display of various models and colours of sunglasses. The image illustrates the difference between different and various.
Various models and colours of sunglasses

Usually, the preposition from comes after different: Her latest novel is very different from anything she has written before. However, some writers prefer than after different. I would use than only with the comparative form: These two are more different than those.  Different than is common in US English. Sometimes I also see different to, which seems to be more common in British English, but you should avoid using different to in writing.

I recommend that you write different when you want to emphasise that there really is a difference. And write from instead of than or to! Write various to indicate that there are several types that are different from each other, that there is a variety of things.

Experience or experiences?

2023-03-27 / / 0 Comments

It may be difficult to understand the difference between experience and experiences.

Experience has two meanings. The first is something that has happened to you. You might say, I had a strange experience on my way to work this morning.

This experience can take the plural form, experiences:

He talked about his bad experiences with cheap hotels.
You wouldn’t believe me if I told you about my experiences in the Himalayas.

The other meaning of experience is what you have learnt from studies or work or from familiarity with something. This is what you would write in your CV. Experience in this case is an uncountable noun; it cannot be used in the plural.

You must have at least five years of teaching experience.
In my experience, this is a very good car.

Experience of computing is always valued

Experience can also be a verb:

She experienced a sense of being valued for her brains and not only for her beauty.

Economy or economics?

2023-02-27 / / 0 Comments

What’s the difference between economy and economics?

ECONOMY

Economy comes from a Greek word meaning household management.

One definition (from investopedia.com) is that economy is ”a complex system of interrelated production, consumption, and exchange activities that ultimately determines how resources are allocated among all the participants”. A government may look at different ways to stimulate the economy.

Another definition of economy is careful management of available resources. We can talk about the fuel economy of a car.

(You can read about the adjectives economic and economical here.)

ECONOMICS

According to wikipedia.org, economics is “the social science that studies the production, distribution, and consumption of goods and services”. Economics focuses on how economies work.

Adam Smith, ”the father of economics”, defined economics as the science of wealth.

Economics is usually divided into two disciplines:

Macroeconomics looks at how the economy as a whole works, how economies grow, change, and go through cycles. This can be about inflation, unemployment rates, monetary policy, foreign trade, etc. 

Microeconomics looks at how supply and demand change over time, how people and businesses work, how people react to changes in prices, and how they make financial decisions.

Alternate and alternative

2023-01-30 / / 0 Comments

Alternate and alternative are sometimes confused, especially in American English. Is there a difference between alternate and alternative?

ALTERNATE

The adjective alternate means every second, every other.
We agreed to take the car to work on alternate days.

The verb alternate means fluctuate, take turns, occur after each other repeatedly.
Sunny days alternated with days of rain.

As a noun, alternate means a substitute, for example in a game or in a film.

In North American English, alternate is often used as a synonym of alternative.

The verb is pronounced as [-eit] at the end, while the adjective and the noun end with [-it].

ALTERNATIVE

The adjective alternative has two meanings. The first is different or possible.
There are several alternative methods to solve the problem.

The image shows a sign in Italian leading to all directions. This is to illustrate alternative or alternate.
You have several alternative routes in all directions

The second meaning relates to something departing from traditional norms.
They chose to lead an alternative lifestyle.

The noun alternative refers to a possibility or option.
You have two alternatives: Stay in bed and read a good book or go jogging round the lake.

In North American English, alternate is often used as a synonym for alternative.

Are you grateful or thankful?

2022-12-29 / / 0 Comments

We use grateful and thankful to express our thanks for something. Even if the two words are often used interchangeably, there is a difference between them. So, what is the difference between grateful and thankful?

GRATEFUL

Grateful is used to express our gratitude when somebody is kind to us or helps us in a way that will have a long-time effect.

Many thanks for helping us move into our new flat. We are so grateful.
I am particularly grateful to my supervisor for her support and encouragement.

You can feel grateful when you are in a third-world country and realise that at home you have access to fresh air and clean water.

You can use grateful when you make a request in a formal letter:

I would be grateful if you would send me your latest brochure.

THANKFUL

Thankful is used when you feel relieved that something dangerous or unpleasant did not happen.

We had a burglary last week. I’m so thankful that my computer was not stolen.
My brother had a nasty car accident. We are all thankful that he was not seriously injured.

A damaged car is being lifted on to a lorry. The image illustrates the difference between grateful and thankful.
A nasty car accident

You are also thankful when somebody has done something and the situation would have been much worse if they had not done anything.

To sum up, if you are grateful, you express gratitude to somebody for something they have done or given and if you are thankful, you feel relief or happiness over something.

The corresponding nouns are gratitude and thankfulness.

Content or contents?

2022-11-29 / / 0 Comments

Both content and contents refer to something contained in something else. So, what’s the difference between them?

Content is uncountable; you cannot have it in the plural. It’s about the whole of something in something else.

The content of her speech really touched the audience.
He has carried out research on the fat content of frozen food.

Content providers supply material such as text, images or music, for use on websites.

In a book, content refers to all the text in a book, but contents is the list, usually at the beginning of the book, that presents the chapters of the book and what page each chapter starts at.

Obviously, contents is a countable noun – we use the plural form. We can identify the separate parts or at least understand that they are there.

He put the flask to his mouth and drank the contents.

The nouns content and contents have the stress on the first syllable.

Content pronounced with the stress on the last syllable is an adjective. This content means happy, satisfied, pleased.

He seemed very content with his new job.

Content with the stress on the last syllable can also be a verb:

I was terribly hungry but realized that I had to content myself with some wine and a small canapé or two.

Assure, reassure, ensure and insure

2022-10-30 / / 0 Comments

Even if these words all have something to do with being sure, they are easily confused.

  • Assure means to tell someone that something will happen or that something is definitely true.

My doctor has assured me that I will be able to read without glasses after my surgery.

  • To reassure somebody means to  make them feel less worried or frightened about a problem.

They reassured us that they would look into the matter.

  • Ensure means to make sure that something will (or will not) happen.

Please ensure that all windows are closed and all doors are locked before you leave the building.

  • Insure means to buy insurance to protect against something bad happening to you or your possessions.

You’d better insure your gear before you go hiking in the mountains.

A man wearing a large rucksack is hiking in the mountains. The image illustrates the idea of insuring gear before doing something adventurous.

Discrete or discreet?

2022-09-23 / / 0 Comments

What is the difference between discrete and discreet?

The  two words sound the same and they look almost the same, but they have very different meanings.

Discrete means separate, distinct, individual, disconnected.

With the lens out of focus we get a number of discrete colour blobs.

We can talk about the discrete parts of a network system.

In mathematics and statistics, a discrete variable is obtained by counting and a continuous variable is obtained by measuring.

Discreet means unobtrusive, cautious, tactful, diplomatic, considerate, not attracting attention.

If a friend tells you something confidential, you should be discreet with that information and not tell anybody else.
