For instance, take the words affect and effect. Spoken quickly (or carelessly) enough the two words sound very much the same. And yet the meanings of the words are quite different.
Affect is only a verb (to affect) which means to influence. Effect is both a noun (effect) which means result and a verb (to effect) which means to bring about. The best way to identify the proper word to use is to substitute the word with each of these three definitions. Whichever one makes the most sense indicates the proper word to use.
Let’s examine the sample sentence in the graphic above. If we replace the word affects with each of the three definitions we just entertained, we should spot the correct use rather easily.
Placing these two metals in physical contact creates a galvanic couple which in turn results the corrosion rate of the anodic piece.

If the word is used as a noun, obviously you should choose effect (singular) or effects (plural). It’s the use of the verb that attends problems. And in that case just substitute the definition and see which one fits better. Affect your knowledge for greater effect, and you’ll see your writing and the representation that makes of you and your brands improve.
