illāc (not comparable)[1]
Etymology
It is from Latin illā (“by that way”) + -ce, the adverb illā with the particle ⟨-ce⟩;[2][3] Wiktionary explains it from the ablative of illic1 (“that one”) with via (“way”) understood.[1] De Vaan lists it, from Plautus on, among the adverbs formed from ille (“that”), the pronoun that replaced older ⟨olle⟩.[4]
Earliest recorded meaning
De Vaan and the TLL record it first in Plautus,[4][5] who has angiporto illac per hortum circuit, “that way, through the alley and the garden, he went round”.[5][6]
Semantic evolution
It means by that way, along that side, in that direction.[2][7] Paired with hac it means this way and that: Terence has hac illac circumcursa, and Plautus hac iter faciundumst, nam illac lumbifragiumst, “we must go this way, for that way there's a broken back”.[6][5] It can also mean simply there, and figuratively Cicero writes that all the bad citizens illac facere, are on that side, Caesar's.[5][3] Tertullian uses sive hac sive illac, in one way or the other.[7][5] The TLL finds it from Plautus to Augustine, apparently not later, and notes that Gregory of Tours lacks it.[5] Medieval British writers use it again for by that way and in hac illac, this way and that.[8] It is the source of Italian là, French là and Spanish allá.[5][7]
