per (implying the uninterrupted continuance of an action with reference to a space of time; e.g., per eos dies, per idem tempus): in (with ablative denoting the time within the space of which anything has occurred). In many cases by the ablative, especially with the name of a certain employment, office, etc.; e.g., during his office as military tribune (= while he was military tribune), tribunatu militum. ☞ Per must not be used, but in, of things taking place in, but not through the whole space: thus “six times during the year,” [which is, however, an inaccurate use of “during”], sexies in anno, not per annum (Krebs); but inferior writers say per; e.g., Pallad., medica quater vel sexies potest per annum recidi; also, per is right when it is denied that anything took place at all during a space, nulla res per triennium nisi ad nutum istius est judicata, Cic.: inter (litterally,” between,” denotes an occurrence coinciding with an act; e.g., during the meal, inter cenam; so inter bibendum, etc.): super (litterally, “over,” denotes an occurrence that accidentally happened whilst an act was going on, e.g., during the meal, super cenam, super epulas, i. e., at dinner = whilst in the act of dining, supping, etc.). In other cases it is rendered by a participial construction; e.g., during my absence, me absente: during my lifetime, me vivo: even during the war, bello nondum confecto; or by “dum” with a verb in the passive voice, e.g., during the war, dum bellum geritur (i. e., whilst the war was carried on).
