(30) Procul.
Procul is formed from pro by the KO-suffix (ch. xi. § 11), and some L-suffix.
(31) Prope.
Prope adds to prō the particle -pe. For Superl. proxime we should expect prop-(i)s-ime (ch. iv. § 2).
(32) Propter.
Propter, near, on account of, is formed from prope by means of the suffix -tero-, as praeter from prae, circiter from circum.
(33) Rě-.
Re-, back, has a by-form red-, with the addition of the particle -de (§ 1), which in class. Lat. remains in red-eo, &c., but is before a consonant discarded for re- in reduco (O. Lat. red-duco), &c. From re- was formed the Adverb retro, like in-tro, ci-tro, ul-tro.
(34) Secundum.
Secundum, according to, close behind, is the Adverbial Acc. Sg. Neut. of secundus, following (ch. vi. § 18). In plebeian Latin secus (Nom. Sg. Masc. of an Adj.-stem seco-, "following") was used for secundum. The Adverb secus of phrases like secus accidit, non secus atque (Comp. sequius) has been referred to this Preposition on the theory that it originally meant "following but coming short of," "less."
(35) Sǐně.
Sine for sene, from s(w)e-, the Reflexive Pronoun-stem (ch. v. § 1) and the particle -ne (§ 1). In Early Latin there was another Preposition with the sense of "without," sed, later se (ch. ii. § 9), an Abl. form of the same Pronoun; e.g. se dolo, without guile (whence the Adv. sedulo, ch. vii. § 6), se fraude esto "let it be without hurt," "it shall be free from penalty," are phrases of common occurrence in Laws of the Republic.
(36) Sub.
Sub is I.-Eur. upō (Gk. ὑπό for ὐπό) with a prefixed particle s. Sub-ter and sub-tus are formed from sub as in-ter and in-tus from in.
(37) Super.
Super is I.-Eur. upĕr (Gk. ὑπέρ for ὐπέρ) with a prefixed particle s. Super-ne adds the particle -ne (§ 1). Suprā is an Abl. Sg. Fem. (ch. vii. § 4).
(38) Těnǔs.
Tenus is Adverbial Acc. Sg. of a Neuter S-stem tenus, -eris, derived from the root ten-, to stretch, and meaning in old Latin "a cord," e.g. Plaut.
pendebit hodie pulcre; ita intendi tenus.
Prō-tenus, protinus, a Compound of this Preposition, had the sense of (1) "forward," "onward" (of space or time), e.g. en ipse capellas Protenus aeger ago, Virg.; sic vives protinus Hor.; (2) without interval of space, e.g. Virg. A. iii. 416:
cum protinus utraque tellus Una foret,
of the traditional connection of the Italian and Sicilian shores; (3) without interval of time, forthwith (its usual sense).
(39) Trans.
Trans is connected with the Verb trare of in-trare, pene-trare. On the change of trans-mitto to tras-mitto, tra-mitto, see ch. ii. § 3; ch. x. § 20.
