• WITHIN

1. preposition, intra (within a space or time): inter (during a time, refers only to time past, time which elapsed while anything happened, not the point from and to which, which is denoted by intra, withinand still before the expiration of a period; both followed by an accusative); in with an ablative (in a time, chiefly of shorter periods, and when no numeral is connected with the time; e.g., within an hour, in hora; within a year, in anno; for which we find, also, anno vertente, in the course of the year; Vid: Schütz. Lex. Civ. in v. Vertens).

2. adverb, intus (toward the interior): interius (in the midst or interior; opposed to exterius): intrinsecus (toward the inner part, on the inner side; opposed to extrinsecus, exterius); ex interiore parte; ab interioribus partibus (from within; opposed to extrinsecus, ab exterioribus partibus): ☞ intra and intro, in this sense, are not classical.
