The
Old English (up to 1150)D records two verbs spelt
root (and pronounced like
boot), and no fewer than ten verbs spelt
rout (and pronounced like
bout). An overlap occurs in the meaning 'to poke about', which can be either
root about or
rout about, each pronounced in its own way. Choice depends largely on regional identity. Of the many other meanings of these words,
root for (= encourage by applause) is mainly confined to American slang but is occasionally heard in Britain.
