capercaillie: [16] The name of the capercaillie, a very large species of grouse, means literally ‘horse of the woods’ in Scots Gaelic. The Gaelic form of the word is capalcoille, a compound formed from capall ‘horse’ (probably borrowed from Latin caballus ‘horse’, source of English cavalier) and coille ‘woods’.
