2. By a change of the termination of the verb, into se, ce, sion, tion, ation, or ition: as, expand, expanse, expansion; pretend, pretence, pretension; invent, invention; create, creation; omit, omission; provide, provision; reform, reformation; oppose, opposition. These denote either the act of doing, or the thing done.
3. By the adding of er or or: as, hunt, hunter; write, writer; collect, collector; assert, assertor; instruct, instructer, or instructor. These generally denote the doer. To denote the person to whom something is done, we sometimes form a derivative ending in ee: as, promisee, mortgagee, appellee, consignee.
4. Nouns and Verbs are sometimes alike in orthography, but different in pronunciation: as, a house, to house; a use, to use; a reb'el, to rebel'; a rec'ord, to record'; a cem'ent, to cement'. Of such pairs, it may often be difficult to say which word is the primitive.
5. In many instances, nouns and verbs are wholly alike as to form and sound, and are distinguished by their sense and construction only: as, love, to love; fear, to fear; sleep, to sleep;—to revise, a revise; to rebuke, a rebuke. In these, we have but the same word used differently.
IV. Nouns are often derived from Participles in ing; as, a meeting, the understanding, murmurings, disputings, sayings, and doings: and, occasionally, one is formed from such a word and an adverb or a perfect participle joined with it; as, "The turning-away,"—"His goings-forth,"—"Your having-boasted of it."
SECTION III.—DERIVATION OF ADJECTIVES.
In English, Adjectives are derived from nouns, from adjectives, from verbs, or from participles.
I. Adjectives are derived from Nouns in several different ways:—
1. By the adding of ous, ious, eous, y, ey, ic, al, ical or ine: (sometimes with an omission or change of some of the final letters:) as, danger, dangerous; glory, glorious; right, righteous; rock, rocky; clay, clayey; poet, poetic, or poetical; nation, national; method, methodical; vertex, vertical; clergy, clerical; adamant, adamantine. Adjectives thus formed, generally apply the properties of their primitives, to the nouns to which they relate.
2. By the adding of ful: as, fear, fearful; cheer, cheerful; grace, graceful; shame, shameful; power, powerful. These come almost entirely from personal qualities or feelings, and denote abundance.
