Century Dictionary and Cyclopedia

1. Together.
2. Identical numerically; one in substance; not other; always preceded by the definite article or other definitive word (this or that). In this sense, same is predicable only of substances (things or persons), or of other kinds of objects which, having individuality are for the purposes of speech analogous to individual things, especially places and times. It is a relative term, implying that what comes to mind in one connection and what comes to mind in another connection are one individual or set of individuals in existence.
3. Of one nature or general character; of one kind, degree, or amount: as, we see in men everywhere the same passions and the same vices; two flames that are the same in temperature; two bodies of the same dimensions; boxes that occupy the same space. Same, used in this way, expresses less a different meaning from def. 1, than a different (and often loose) mode of thinking; the thought is often that of equality rather than that of identity.
4. Just mentioned, or just about to be mentioned or denoted: often used for the sake of emphasis or to indicate contempt or vexation.
5. However; nevertheless; still; yet: used to introduce a reservation, explanation, or fact not in conflict but in contrast with what has been said.
