Homophones: these are words having a similar sound, or pronunciation but with a totally different meaning. Homophones are quite common in English and are often misleading to the listeners.

In some cases, there are many words having a similar sound while pronunciation but have different meanings. One such typical example includes words like affect and effect.

Affect vs Effect 

The main difference between Affect and Effect is that ‘affect’ is commonly used as a verb while ‘effect’ is used as a noun. Affect means ‘to change’ or ‘to have an influence’. ‘Effect’ refers to a consequence of an action or a result of an action. Both of them are homonyms and are used regularly in daily life.

Affect‘ comes from the Latin term ‘afficere’ which means to influence someone mainly used as a verb. Affect is generally used when an alteration is to be shown or when something is influenced by a specific thing. It is mostly used as an action verb used to describe someone’s action to describe a change.

‘Effect’ also comes from a Latin term ‘efficere’ that refers to change caused by an action or consequence of an action. Effects show the outcome of an action or the change a process has caused. It is mainly used as a noun to describe the outcomes of situations or events.
