Note 13 — DIGRAPHS.
Reading edition
This only applies to occasions on which they indulge in English speech. The Anglo-Saxon WH (written Hw) had formerly a more palatal sound, and while passing into ʍ had a tendency to become f. In the Aberdeenshire dialect it has remained f; e.g., fan, far = when, where. Many such eccentric permutations are amusingly anaglyptographed in that monument of the “Aberdeenshire Doric,” Johnny Gibb o’ Gushetneuk. (Ed’bro’: D. Douglas.)
