3.  The adjective, and not the adverbial, form should be used after a copulative verb, since adverbs cannot modify substantives:  [I feel bad; not, I feel badly].

4.  Two negatives imply an affirmative.  Hence only one should be used to denote negation:  [I have nothing to say.  I have no patience with him].

PREPOSITIONS

+76.  Classes of Prepositions.+—­The simple prepositions are:  at, after, against, but, by, down, for, from, in, of, off, over, on, since, through, till, to, under, up, and with.

Other prepositions are either derived or compound:  such as, underneath, across, between, concerning, and notwithstanding.

+77.  Suggestions concerning the Use of Prepositions.+—­Mistakes are frequently made in the use of the preposition.  This use cannot be fully discussed here, but a partial list of words with the required preposition will be given.

afraid of. agree with a person. agree to a proposal. bestow upon. compare to (to show similarity). compare with (to show similarity or difference). comply with. conform to. convenient for or to. correspond to or with (a thing). correspond with (a person). dependent on. differ from (a person or thing). differ from or with (an opinion). different from. disappointed in. frightened at or by. glad of. need of. profit by. scared by. taste of (food). taste for (art). thirst for or after.

Like, originally an adjective or adverb, is often, in some of its uses, called a preposition.  It governs the objective case, and should not be used as a conjunction:  [She looks like me; not, She looks like I do].  The appropriate conjunction here would be as:  [She speaks as I do].

The prepositions in and at denote rest or motion in a place; into denotes motion toward a place:  [He is in the garden.  He went into the garden].

+78.  Prepositional Phrases.+—­The preposition, with its object, forms what is termed a prepositional phrase.  This phrase is adjective in force when it modifies a substantive; and adverbial, when it modifies a verb, adjective, or other adverb:  [In the cottage by the sea (adjective).  He sat on the bench (adverb)].

Some prepositions were originally adverbs; such as, in, on, off, up, and to.  Many of them are still used adverbially or as adverbial suffixes:  [The ship lay to.  A storm came on].
