Origin & History of “channel”
Channel and canal are ultimately the same word. their common ancestor was Latin canālis ‘groove, channel’, a derivative of canna ‘pipe’ (source of English cane). This passed into Old French as chanel, which English took over as channel. But then in the 15th century English acquired canal, either directly from Latin, or from French canal, which was itself remodelled on the Latin form – it is not clear which.
