CÉT continues in Modern Irish as CÉAD, which means 'a hundred (100)'. In early Irish, though, the word could denote 120. In other medieval languages too, words which now refer to 100 were used to mean 120. In order to avoid confusion, English eventually adopted the terms 'long hundred' or 'twelfty' for 120, and in Ireland 120 became known as GALLCHÉT 'the foreign hundred'. There are, however, some legal references which show CÉT itself being used with this meaning, e.g. 'se fichit in gach ced' (six twenties in every 'cét'; 23Q6,51b43).
