coudrier

from the suffix -ier with coudre the name of the hazel tree (12th century); in Old French codre (1160-70) (continued by the Gallo coude, Burgundian queudre), from coldre (attested in Judeo-French, 11th century, glossary of Rashi), from a colre, from Vulgar Latin colurus (cf. Romansh coller), metathesis of Latin corulus, influenced by the Gaulish collos, comparable to Breton kollenn, Irish coill. Comes directly from the Gaulish l'occitan còila, "hazel twig".
