Pronunciation

Etymology

It is inherited from Latin intrō (“inside, to the inside”).[2][3][4][1] The TLIO adds the influence of inter (“between”).[5] Romanian întru is the same word, and REW also cites Old Spanish entro (“until”).[3][6]

The Latin adverb and intrā (“within”) are old ablatives of an adjective *interus (“inner”), formed from in (“in”) with the suffix ⟨-ter⟩ of contrast and parallel to exterus (“outer”).[3][2][7] It goes back to Proto-Indo-European *h₁énteros (“inner”), and Nocentini compares Ancient Greek ἔντερον (énteron, “intestine”).[1][3]

entroterra is modelled on German Hinterland, and entrobordo on fuoribordo.[2][3]

Earliest recorded meaning

The first record is in the Ritmo di sant'Alessio, a poem from the Marche of the late 12th century, as an adverb “inside”.[5] DELI dates the adverb to Bono Giamboni (before 1292) and the preposition “inside, in” to Cecco Angiolieri (before 1313), who wrote that if he met his lady entro la via (in the street) he would hardly know her.[2][8]

Semantic evolution

Old Italian used entro with many other words: d'entro “from inside” and “inner”, per entro “through”, entro a and entro in, as in Dante, Petrarch and Boccaccio.[5][9][10] The time sense “before the end of” is recorded in Daniello Bartoli, before 1685.[2] Tommaseo noted that the adverb without a following noun was by then used only in verse.[9] Today the time sense is the usual one, and the spatial sense is literary.[11][12][1]
