Origin of affect

Usage Note: Affect and effect are often confused because they sound alike and have related meanings. First, bear in mind that there are two words spelled affect. One means “to put on a false show of,” as in She affected a British accent. The other affect, the one that is confused with effect, is both a noun and a verb. As a noun it is uncommon and means roughly “emotion.” It is pronounced with stress on the first syllable rather than the second. Note that affect does not have a noun sense meaning “an influence that brings about a change.” As a verb, affect is most commonly used in the sense of “to cause a change in:” the ways in which smoking affects health. The verb effect means “to bring about or execute”: medical treatment designed to effect a cure. Its corresponding noun means “a result.” Thus if someone affects something, there is likely to be an effect of some kind, and from this may arise some of the confusion. People who stop smoking will see beneficial health effects, but not beneficial health affects. The verbs produce important differences in meaning. The sentence These measures have been designed to effect savings implies that the measures will cause new savings to come about. Using affect in the very similar sentence These measures will affect savings implies that the measures will cause a change in savings that have already been realized.

Origin of affect
Middle English affectenfrom Latin affectāreto strive afterfrequentative ofafficereaffect-to affect, influence ; see affect1.
These verbs mean to produce a mental or emotional effect. To affect is to act upon a person's emotions: Adverse criticism of the book didn't affect the author.Influence implies some control over the thinking, actions, and emotions of another: “Humanity is profoundly influenced by what you do” (Pope John Paul II). To impress is to produce a marked, often enduring effect: “The Tibetan landscape particularly impressed him” (Doris Kerns Quinn). Touch usually means to arouse a tender response: “The tributes [to the two deceased musicians] were fitting and touching” (Daniel Cariaga). Move suggests a profound emotional effect: The account of her experiences moved us to tears.Strike implies keenness or force of mental response: I was struck by the sudden change in his appearance.
Affect and effect are sometimes confused. Affect conveys influence over something that already exists, but effect indicates the manifestation of new or original ideas or entities:
“...new policies have effected major changes in government.”
“...new policies have affected major changes in government.”
The former indicates that major changes were made as a result of new policies, while the latter indicates that before new policies, major changes were in place, and that the new policies had some influence over these existing changes.
The verbal noun uses of affect are distinguished from the verbal noun uses of effect more clearly than the regular verb forms. An affect is something that acts or acted upon something else. However, an effect is the result of an action (by something else).
