Where did ‘decuman’ come from?
‘What made you chase that hare?’ asked my husband with rare geniality. John Ruskin was to blame. He asked James Russell Lowell where he found decuman, meaning ‘big wave’. The line ‘Spume-sliding down the baffled decuman’ came in Lowell’s ‘The Cathedral’ (1870) about Chartres. Lowell was Longfellow’s big-beardy successor as professor of belles-lettres at Harvard.
