Usage Note

Of is sometimes added to phrases beginning with the adverb how or too followed by a descriptive adjective: How long of a drive will it be? It's too hot of a day for tennis. This construction is probably modeled on that in which how or too is followed by much, an unquestionably standard use in all varieties of speech and writing: How much of a problem will that cause the government? There was too much of an uproar for the speaker to be heard. The use of of with descriptive adjectives after how or too is largely restricted to informal speech. It occurs occasionally in informal writing and written representations of speech. couple, off.

Usage

See off

Spelling Note

Because the preposition of, when unstressed ( a piece of cake ), and the unstressed or contracted auxiliary verb have ( could have gone, could've gone ) are both pronounced [uh, v] or [uh] in connected speech, inexperienced writers commonly confuse the two words, spelling have as of ( I would of handed in my book report, but the dog ate it ). Professional writers have been able to exploit this spelling deliberately, especially in fiction, to help represent the speech of the uneducated: If he could of went home, he would of.
