John Morris Jones,
A Welsh Grammar, Historical and Comparative
(1913)
“ In modern writing the division of syllables where required, as at the end of a line, is made to follow the etymology rather than the sound; thus it is usual to divide can-u ‘to sing’ so, can being the stem and u the ending, instead of ca-nu, which is the true syllabic division. In the case of more than one written consonant the division is usually made to follow the sound; thus, can-nu ‘to whiten’, plen-tyn ‘a child’, the etymological division being cann-u, plent-yn. Ml. scribes divided a word anywhere, even in the middle of a digraph. ”
