catamaran (French)

Where does "catamaran" come from?

The French noun 'catamaran' was borrowed from English 'catamaran'[1], which traces its roots back to Tamil 'கட்டுமரம்' (kaṭṭumaram)[2]. This Tamil term is a compound formed from 'கட்டு' (kaṭṭu), meaning 'to tie', and 'மரம்' (maram), meaning 'tree, wood'[2][3]. The historical lineage of the second element reaches further back through Old Tamil '𑀫𑀭𑀫𑁆' (maram) to Proto-Dravidian '*maran'[4], while the first element connects to Proto-Dravidian '*kaṭ-'[5].
