Andiron
Origin
Middle English anderne (aunderne, aundyre), from Old French andier (mod. landier), from Gaulish anderon 'calf' (compare Irish ainnir 'young woman', Welsh anner 'heifer, cow-calf', enderig 'bull-calf, ox', Breton annoar 'heifer, cow-calf'), because calves rather than dogs figured prominently on ancient Celtic firedogs. Altered in form under the unfluence of iron.
