(2) pur ‘very’, as pur-ẟu, pur-wynn r.m. 151, pur-goch 154; pur-iawn ‘very well’, now púri̯on. It now forms loose compounds mostly, as pur dda ‘very good’. Used after its noun as an ordinary adj. it means ‘pure’.
156. i. The first element of a compound may be a prefix, which was originally an adverb or preposition. Some other vocables of adj. or noun origin have become mere prefixes; for convenience of reference these are included in the following list. Where the mutation of the initial after the prefix is fairly regular, it is noted in square brackets. Most of the prefixes form verb-compounds also, and some are oftener so used; hence it is convenient to include verbal nouns and verbs in the examples.
