“one another” in Latin

alius alii or alium; of two, alter, alteri, or alterum (= one... the other); inter se, among or between themselves, is used when the predicate is referred only to the personality of a subject of the third person plur., named in the same clause, in the nominative or accusative case, rarely in any other: ☞ se inter se is not Latin; Vid: Gernh., Cic., Lael., 22, 82; Handrianus, Tursell., 3, p. 387, sq.): inter ipsos (among themselves, when the predicate of a proposition is to be referred to such a subject exclusively, and in opposition to all others; the subject is then mentioned in the same clause, either in the genitive, dative, or ablative, or in the clause immediately preceding): mutuo (mutually; ☞ invicem here would be unclassical, vicissim has a different meaning): ultro et citro, ultro citroque, ultro citro (hither and thither, on both sides). ☞ Ultro citro is probably post-Augustan; Vid: Handrianus, Tursell., 2, p. 86, sqq.): they help one another, alter alterum adjuvat; alius alii subsidium ferunt: they keep nothing from one another, nihil quidquam secretum alter ab altero habet: they (two armies) did not observe one another, neutri alteros cernebant: they blamed one another, alius alium increpabant: to love one another, amare inter se; inter se diligere (☞ invicem or mutuo diligere not classical: vicissim diligere, formed by the moderns from the misunderstood passage, Cic., Lael., 9, 30, is wrong): we love one another, amamus inter nos (☞ not amamus nos inter nos): to look at one another, to fear one another, etc., inter se aspicere, timere, etc.: to strike one another, alter alterum verberibus caedit (PROP., with cudgels): inter se confligere (figuratively, of battle): to be at variance with one another, inter se discordare, dissidere, dissentire: to kiss one another, mutua dare oscula: to kiss and embrace one another, osculari et amplexari inter se (Plaut., Mil., Glor., 5, 40): to render services to one another, officiis mutuo respondere: to eat one another, mutua carne inter se vesci: to meet one another, sibi occurrere or obviam fieri: to shoiv kindness to one another, ultro citroque beneficia dare et accipere: to send messengers to one another, nuncios ultro citroque mittere.
