Ah, the old affect vs. effect condundrom. Even experienced writers need an occasional refresher on this tricky grammar rule. Here's a tip to remember the difference between the meaning of each word. Affect means to act on or to produce a change in. Think "a" for affect and "a" for act on. (Ex: The hot weather affected the flowers.) Effect, on the other hand, means something that is produced by a cause or result. (Ex: The effects of the snow caused major traffic delays.) Now hopefully, the effects of this little lesson will affect what you write!
