Variants ending in -e can also be interpreted (with an accent) as forms of uré. DMF, Godefroy and TL, as well as the FEW, provide separate articles for both possibilities, with the two (or even three) entries (cf. the cognate references) being entirely synonymous. As none of the A-N attestations feature the word with an -e in a rhyming position, the validity of neither option can be tested. Consequently the AND conflates the two possible articles into this single entry. For a possible confirmation of the uré reading, see uret1.
According to the FEW, the Latin substantive ora produced the (unattested) verb *orulare, which explains the existence in Anglo-Norman of both ur and urle as quasi-synonymous substantives. Although appearing in mostly the same contexts (and as variants of each other in different manuscripts), urle seems to be attested mostly with reference to clothing.
