alare.

Uncertain. Attested in the Reichenau Glossary. Multiple etymologies have been proposed. Traditionally ambulāre has been regarded as the etymon, possibly via a contracted form *amlāre, with the contraction perhaps due to its use as a military command. However, this is problematic for several reasons. Others have proposed an origin in a Gaulish *aliu, from Proto-Celtic *ɸal-. Compare Welsh elwyf (“I may go”), Cornish ellev (“I may go”), from full grade *ɸel-. A third proposal is that alāre was back-formed from allātus, past participle of afferre, thanks to a reflexive construction like se afferre (literally “carry oneself to”). French s'est allé, for instance, would then be a continuation of *[se allātus est]. All of its attested descendants are (and so presumably alāre was as well) suppletive with vādere, which supplies the present singular and third-person plural, and with īre often supplying the future and conditional forms. Compare the contemporary synonym andāre.
