 Note: ☞ All is much used in composition to enlarge the meaning, or add force to a word. In some instances, it is completely incorporated into words, and its final consonant is dropped, as in almighty, already, always: but, in most instances, it is an adverb prefixed to adjectives or participles, but usually with a hyphen, as, all-bountiful, all-glorious, allimportant, all-surrounding, etc. In others it is an adjective; as, allpower, all-giver. Anciently many words, as, alabout, alaground, etc., were compounded with all, which are now written separately.
