From -er- + -ei.

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.[1]



  1. Used with a stem to form the first-person singular conditional of regular -are and -ere verbs.
