Grammar note:    There is often confusion between the words “effect”  and “affect.”   In the early stages of learning English, students are taught that the word beginning with “e” is a noun and the word beginning with “a” is a verb.  In general, this way of remembering which spelling goes with which works very well, because “effect” is most commonly used as a noun.  However, “effect” has a meaning as a verb too.  The meaning is different from the meaning of “affect,” and the two words still need to be differentiated.  “Effect” as a verb means “to bring into being or operation.”  It is most commonly used in connection with the word “change,” but it is also used with words like  “improvement,” “settlement,”  “agreement,” “transition, “” and “”rescue.”
