The first men in the state [Vid: “CHIEF men. “] The first point, caput alicujus rei: summa alicujus rei: cardo alicujus rei (on which all turns; Verg. and Quint.): momentum (ῥοπή, the critical, decisive point).

2. adv. ☞ The three first, tres primi (e.g., tribus primis diebus, Caes., B. C. 1, 18, which may help to banish the foolish notion that accuracy requires us to say “the first three”): He considered that the first thing was, etc., nihil prius faciendum putavit. ☞ The Latins regarded as an apposition the closer definition, which in English, is expressed by a relative proposition, or by an infinitive. I was the first who did it, or the first to do it, primus feci. If only two are spoken of, the first is prior; opposed to to the second, posterior; or, if there be a reference to two subjects already named, ille (the second being expressed by hic). If first = earliest, ultimus is used; ab ultima origine: the first (= next) after anybody, proximus. If the first thing = the most important thing, summum or caput is used; e.g., the first step toward a happy life is, caput est ad bene vivendum: he considered that the first thing should be, nihil prius faciendum putavit. To be the first in anything, initium alicujus rei facere, capere, ducere (to do it first, to make a beginning); principem esse in re; optimum, praestantissimum esse in aliquo genere; alicujus rei principatum obtinere (to be the most excellent): let us be neither first nor last, nec duces simus, nec agmen claudamus: each wishing to be the first (on the road), cum sibi quisque primum itineris locum peteret: to be the first of his class, classem ducere (Quint., 1, 2, 28): to be the first after the king, secundum imperii gradum tenere: I am the first (to get up) in the morning, and the last at night (in going to bed), primus cubitu surgo, postremus cubitum eo.
