Latin minimal pairs distinguished only by vowel length

[Iáson]

venīre ('come') vs vēnīre ('go for sale/be sold').

venit (pres.) and vénit (perf.)

Also for veniō, the imperative venī vs. perfect vēnī.

 

[Iáson]

ēlāte voc. sg. masc. p.p.p. efferō.
elatē fem. sg. nom. 'fir tree' (loan from Greek ἐλάτη).
Hence also ēlātīs vs. elatīs.

[Iáson]

Granted they're not distinguished by the length of a single vowel, but they are distinguished only by vowel length.
