-erei

Italian

Etymology

From -er- + -ei.

• -er- is the reduced form of the Italian infinitive endings -are and -ere.
• -ei stems from Vulgar Latin hĕbui / (h)ĕ(bu)i, which stems from classical Latin habuī, first-person singular perfect of habeō.

The Italian conditional mood stems from a Vulgar Latin periphrastic verb form consisting of infinitive + perfect of habere. Example: Italian loderei (“I would praise”) stems from Vulgar Latin laudare + hĕbui. See also Italian grammar, section Conditional mood in the English Wikipedia.
