Iaith rymus Môn geir yma, ar ffurf casgliad o ddywediadau, rhigymau a geiriau, oll at bwrpas, wedi eu casglu dros gyfnod o ddeugain mlynedd gan Siôn Gwilym, Llannerch-y-medd. Llafur cariad am iddo wirioni'n llwyr pan oedd yn ifanc iawn ar wreiddioldeb hwyliog a dawn dweud y gymdeithas werinol a gwledig y'i magwyd ynddi.
This is a collection of the richness of the Welsh language, as found in the words and sayings of the people of Anglesey. They have been collected by Siôn Gwilym, Llannerch-y-medd who, from an early age, doted on the originality of the dialect of the inhabitants of the rural community in which he was raised.
