Difference Between Affect and Effect
Affect and Effect :
Being two words with not only very similar meanings but also extremely similar pronunciations, these two words have been the source of utter confusion for many a English student worldwide. Not only for students of English, these two words can quite easily be mistaken by even a native speaker of English as the usage of both these words convey very different things under different circumstances.
The word affect, which is based on the Latin word which means “to have influence on” is generally used as a verb. Affect can be used in two main manners as in how something influences a course of action or a sequence of events or how a certain incident may have an emotional or a mental influence on a particular person. For example, when one says
“The contents in that letter affected him in such a way that he burst in to tears immediately after reading it” refers to how the word affect has been used as an emotional influence.
“Heavy rains will affect the outdoor concert” refers to how the word affect has been used to describe the influence that a certain phenomena has on a certain event.
The word affect is also used as a noun, but this is used in a rare and archaic sense. One often see the use of affect in physiology and psychiatry, more often describing the state of a person’s mental state. For example,
“The patient exhibited a flat affect, responding to absolutely nothing.”
Effect on the other hand is more commonly used as a noun. Usually, when something affects something, it creates an effect. The word effect is easily described as a result or a consequence creates by something. One can take the example
“The heavy weather had no effect on his jovial mood”
The above example gives the sense of having an influence on something.
Effect can also mean a state of fulfillment or an accomplishment. For example
“He put his carefully drawn plan in to effect”
Here, the word effect is used to convey an achievement or a fulfillment which he had gained through his plan.
The word effect can be used as a verb as well, often in the meaning “to produce”. For example
“She is a great woman who effected a change in the thinking patterns of men”
Therefore, one can see how the words affect and effect are used in very different contexts
