Century Dictionary and Cyclopedia

1. A; a certain; one: noting a person or thing indefinitely, either as unknown or as unspecified.
2. In this sense often fallowed by a correlative other or another.
3. A certain indefinite or indeterminate quantity or part of; more or less: often so used as to denote a small quantity or a deficiency: as, bring some water; eat some bread.
4. In logic, at least one, perhaps all; but a few logicians sometimes employ a semidefinite some which implies a part, but not all. As commonly used in logic, a statement about some of a class, say that “some S is P,” means that it is possible so to select an S that it shall be P; while “every S is P” means that whatever S be taken, it will be P. But when some and every occur in the same statement, it makes a difference which is chosen first. Thus, “every man knows some fact” may mean that, first choosing any man, a fact may then be found which that man knows (which may be expressed by saying that every man knows some fact or other); or it may mean that a fact may be first selected such that, then, taking any man, he will know that fact (which may be expressed by saying that all men know some certain fact). When several somes and alls occur in the same statement, ordinary syntax fails to express the meaning with precision, and logicians resort to a special notation.
5. A certain indefinite or indeterminate number of: used before plural substantives: as, some years ago.
6. Hence A certain number of, stated approximately: in a quasi-adverbial use before a numeral or other word of number: as, a place some seventy miles distant; some four or five of us will be there.
7. A certain person; one.
8. A certain quantity, part, or number, as distinguished from the rest: as, some of them are dead; we ate some of our provisions, and gave away the rest.
9. In this sense some is very commonly repeated, some … some (or, formerly, other some, as in Acts xvii. 18) meaning ‘a number … others,’ or ‘the rest.’
10. The plural some is occasionally used in the possessive.
11. Some, as originally used partitively with numbers (AS. feówra sum, one of four, etc.), has come to be an apparent distributive suffix, as in foursome, sevensome.
12. In some degree: to some extent; somewhat: as. I am some better; it is some cold.
13. As; so; ever: used indefinitely after certain adverbs and pronouns, like so, soever. It remains in modern dialectal use in how some, what some, or howsomever, whatsomever, wheresomever, etc., equivalent to howsoever, whatsoever, wheresoever, etc.
14. A suffix used to form adjectives from nouns or adjectives, as mettlesome, blithesome, lonesome, gladsome, gamesome, gruesome, quarrelsome, toothsome, troublesome, wholesome, winsome. It usually indicates the possession of a considerable degree of the quality named: as, mettlesome, full of mettle or spirit; gladsome, very glad or joyous. As used with numbers, foursome, sevensome, -some is of different origin: see some, adjective
