The _weak verbs_ are those which form the preterite by adding _-ed, -d_, or _-t_ to the present: _love, loved_. There is also infrequently a change of vowel: _sell, sold_; _teach, taught_.

All verbs which form the preterite without the addition of an ending are _strong verbs_. There is usually a change of vowel. The termination of the past participle in _-n_ or _-en_ is a sure indication that a verb is _strong_. Some verbs show forms of both conjugations.

A complete list of _strong_ verbs cannot be given here, but a few of the most common will be given, together with a few _weak_ verbs, in the use of which mistakes occur.

[Footnote 1: Used only in the pa.s.sive sense of "born into the world."]

[Footnote 2: _Drunken_ is an adjective.]

CAUTION.--Do not confuse the preterite with the past participle. Always use the past participle form in the compound tenses.

ADVERBS

+71. Cla.s.ses of Adverbs.+--Adverbs vary much as to their use and meaning.

It is therefore impossible to make a very accurate cla.s.sification, but we may divide them, according to use, into _limiting, interrogative_, and _conjunctive_ adverbs.

_Limiting_ adverbs modify the meaning of verbs, etc.: [He rows _well_].

_Interrogative_ adverbs are used to ask questions: [_When_ shall you come?

He asked _where_ we were going (indirect question)].

_Conjunctive_ adverbs introduce clauses: [We went to the seash.o.r.e, _where_ we stayed a month]. Here _where_ is used as a connective and also as a modifier of _stayed_.

Conjunctive adverbs introduce the following kinds of clauses:

1. Adverbial clauses: [Go _where_ duty calls].

2. Adjective clauses: [This is the very spot _where_ I put them].

3. Noun clause: [I do not know _how_ he will succeed].

Adverbs may also be cla.s.sified, according to meaning, into adverbs of _manner, time, place_, and _degree_. The cla.s.sification is not, however, a rigid one.

Adverbs of _manner_ answer the question How? Most of these terminate in _-ly_. A few, however, are identical in form with adjectives of like meaning: [She sang very loud].

Adverbs of _time_ answer the question When?

Adverbs of _place_ answer the question Where? This cla.s.s, together with the preceding two cla.s.ses, usually modify verbs.

_Adverbs of degree_ answer the question To what extent? These adverbs modify verbs, adjectives, and other adverbs.

+72. Phrasal Adverbs.+--Certain phrases, adverbial in character, cannot easily be separated into parts. They have been called _phrased adverbs;_ as, arm-in-arm, now-a-days, etc.

+73. Inflection.+--Some adverbs, like adjectives, are compared for the purpose of showing different degrees of quality or quant.i.ty.

The comparative and superlative degrees may be formed by adding the syllables _er_ and _est_ to the positive degree. The great majority of adverbs, however, make use of the words _more_ and _most_ or _less_ and _least_ to show a difference in degree: [Fast, faster, fastest; skillfully, more skillfully, most skillfully; carefully, less carefully, least carefully].

Some adverbs are compared irregularly:--

badly } worse worst ill (evil)} far } { farther { farthest forth } { further { furthest late later { latest { last little less least much more most nigh nigher { nigher { next well better best

+74. Suggestions and Cautions concerning the Use of Adverbs.+

1. Some words, as _fast, little, much, more_, and others, have the same form for both adjective and adverb, and use alone can determine what part of speech each is.

(Adjective) He is a fast driver. She looks well (in good health).

(Adverb) How fast he walks! I learned my lesson well.

2. Corresponding adjectives and adverbs usually have different forms which should not be confused.

(Adjective) She is a good student.

(Adverb) He works well.

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].

+75. Equivalents for Adverbs.+

1. A phrase: [The child ran away _with great glee_].

2. A clause: [I will go canoeing _when the lake is calm_].

3. A noun: [Please come _home_. I will stay five _minutes_].

PREPOSITIONS

+76. Cla.s.ses 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_.
