This is one where people tend to muddle up the noun and the verb. The verb has the "e" at the end. This is a fairly common distinction within English, but there appear to be growing numbers of people who either don't know what the difference between the noun and verb forms is, or don't know the difference between a noun and a verb. For those who missed this in primary school: a noun is a naming word - it names an object, concept, idea or person; a verb is a doing word - it speaks of an action. In the classic sentence, "The cat sat on the mat", cat and mat are nouns; sat is the verb which tells what the cat was doing.
