Affect vs Effect And Why The Effects Affect Your Writing

There are 368,000 Google searches every month for affect vs effect.

Clearly, for a lot of people, we have an English language problem here.

The words affect and effect cause a lot of confusion because they sound similar. So let’s look at the cause and effect of the problem.

Learning the difference between affect and effect is easy, once you know that one is a verb and one is a noun.

When we speak, there is no problem with the usage of these two words because they are almost homonyms and we can use facial expressions to make our meaning clear.

I say almost because there can be a slight difference depending on different English language accents and pronunciation.

Affect has a schwa sound whereas effect used a pure vowel sound.

effect |ɪˈfɛkt|

affect |əˈfɛkt|

However, in writing it is vitally important to use the correct parts of speech to phrase cause and effect correctly.

In general, effect is commonly used as a noun and affect is normally a verb but they are commonly confused.

To affect means to have a negative or positive outcome on something or someone, or to make a difference to something. In other words, it is a verb meaning to influence or alter something. It is a cause. 

An effect is a change that is a result or consequence of an action or other cause. In simple terms, it is a result.

Because affect is a verb, it is placed after the subject and can be used in all tenses.

So it will be written as affect, affects, affected or affecting. You have perhaps commonly used affect as a verb in the passive voice. The game was affected by bad weather.

The word effect is a noun meaning the result or outcome.

It always takes an article. Either an, the, or the zero article when it is plural. An effect, the effect, effects.

It can also be preceded by an adjective. A terrible effect, a side effect, a positive effect.

It needs to be a mnemonic device. Or in other words, you need to practice to remember the difference between these two confusing words.
