Forms
vadum n (genitive vadī); second declension[1] A masculine vadus appears in Varro (quoted by Servius), Sallust and Fronto.[2][3]
Etymology
It is inherited from Proto-Italic *waþo-, inherited from Proto-Indo-European *uh₂dʰ-o-, from the root *weh₂dʰ- (“to advance, wade”) of vādō.[4][1] Its short vowel matches that of Old High German watan (“to wade”) and Old Norse vaða (“to wade”), while the long vowel of the verb matches Welsh; so de Vaan sets up a root present with ablaut, and perhaps a noun ⟨*uh₂dʰ-o-⟩ already in Proto-Indo-European.[4] Cognates are wat (“ford”), vað (“ford”) and Old English wæd (“water, lake”).[4][2]
Earliest recorded meaning
Plautus, Rudens, of a girl thrown from a boat: at in vadōst, iam facile ēnābit, “but she's in shallow water; she'll easily swim out”.[2][4]
Semantic evolution
Vadum is water shallow enough to wade, a shallow, and in a river a ford: Caesar notes that the Rhône can be crossed by ford in some places.[2] At sea it is a shoal where ships run aground, and also the bottom or bed of the sea, of wells, drains and rivers (Virgil's Neptune feels the waters stirred from their lowest beds).[2] Poets use the plural for the waters of sea or river, whatever their depth (Catullus: vada salsa).[2] Grattius uses it, after Greek, for a passage in the body.[2] Figuratively a “shallow” can stand for safety or for danger, as for a boat in shallow water.[1]
Döderlein groups it with solum and fundus as words for the natural ground or bottom of something.[5] In medieval Latin it is a river crossing or a ferry service.[6]
