Supplement and complement – and compliment

Supplement and complement are used as nouns and verbs. The adjectives are supplementary and complementary.

SUPPLEMENT

Supplement as a verb means add to, increase.

It is also used as a noun.

Many athletes use herbal supplements.

COMPLEMENT

Complement means complete, harmonise with, bring to perfection.
That tie really complements your suit.

In mathematics, angles are complementary if they add up to 90 degrees and supplementary if they equal 180 degrees.

COMPLIMENT

Compliment as a verb means to praise, to express appreciation or admiration.

It is also used as a noun.

It’s or its?

Writers are sometimes not sure about when to write it’s or its.

IT’S
An apostrophe means that a letter has been left out (sometimes more than one letter).
It’s is the abbreviated form of it is (or sometimes it has).

It’s hard to believe that he is 14 years old (It is hard to believe…).
The book is very thick, but it’s really interesting (it is really interesting).
It’s been a long day (It has been a long day).
It’s got to be true (It has got to be true).

ITS
Its is the possessive form of the pronoun it.

Stockholm is known for its many islands.
The cat was licking its paw.

The cat was licking its paw

The simple rule is this: If you can say it is or it has, then the form with an apostrophe, it’s, is correct.

It’s frightening when the bear opens its massive jaws

The abbreviated form it’s should not be used in formal language – there you should write it is.

What is true about it’s and its also applies to you’re and your, they’re and their or who’s and whose.

Affect or effect?

Affect and effect are two words that easily get mixed up

AFFECT

Affect is mainly used as a verb. It means have an impact on, have an effect on.
The bad weather affected our plans for the evening.

How will the strike affect your job?

The bad weather affected our plans for the evening

EFFECT

Effect is a noun. It denotes the result of an action or an impression.
The effect of his words was immediate.
I liked the sound effects in the film.
The law is still in effect.

To sum up, most often affect is a verb and effect is a noun.

That said, you may – on rare occasions – find affect used as a noun. Then it means something that acts on something else, usually in psychological jargon.

And effect can be used as a verb meaning to produce, bring about something new, often in phrases like ”to effect a change”
