NOTE.  Several adverbs frequently qualify one verb.  Have you walked? Not yet quite far enough, perhaps.  Not, yet, far, and enough, qualify “have walked” understood; perhaps qualifies not; and quite qualifies far.  The adverbs always and carefully both qualify the verb “drive:”  the former expresses time, and the latter, manner.  Once and voluntarily qualify the verb “contributed;” the former expresses number, and the latter, manner.  The word their you need not parse.  The active verb to save has no nominative.  The nouns love and friendship, following in, are in the objective case, and governed by that preposition.

REMARKS ON ADVERBS.

When the words therefore, consequently, accordingly, and the like, are used in connexion with other conjunctions, they are adverbs; but when they appear single, they are commonly considered conjunctions.

The words when and where, and all others of the same nature, such as whence, whither, whenever, wherever, till, until, before, otherwise, while, wherefore, &c. may be properly called adverbial conjunctions, because they participate the nature both of adverbs and conjunctions; of adverbs, as they denote the attributes either of time or place; of conjunctions, as they conjoin sentences.

There are many words that are sometimes used as adjectives, and, sometimes as adverbs; as, “More men than women were there; I am more diligent than he.”  In the former sentence more is evidently an adjective, for it is joined to a noun to qualify it; in the latter it is an adverb, because it qualifies an adjective.  There are others that are sometimes used as nouns, and sometimes as adverbs; as, “to-day’s lesson is longer than yesterday’s.”  In this example, to-day and yesterday are nouns in the possessive case; but in phrases like the following, they are generally considered adverbs of time; “He came [to his] home yesterday, and will set out again to-day.”  Here they are nouns, if we supply on before them.

“Where much [wealth, talent, or something else] is given, much [increase, improvement] will be required; Much money has been expended; It is much better to write than starve.”  In the first two of these examples, much is an adjective, because it qualifies a noun; in the last, an adverb, because it qualifies the adjective better.  In short, you must determine to what part of speech a word belongs, by its sense, or by considering the manner in which it is associated with other words.

An adjective may, in general, be distinguished from an adverb by this rule:  when a word qualifies a noun or pronoun, it is an adjective, but when it qualifies a verb, participle, adjective, or adverb, it is an adverb.
