1. grammatical particle used in conjunction with bod (“to be”) to mark adjectival, nominal, or verbal complements

2. grammatical particle used to change an adjective into an adverb

   yn dda ― well

   yn fawr ― greatly

   yn wir ― truly

This particle causes the soft mutation (lenition) in all consonant sounds except for /r̥/ (spelt <rh>) and /ɬ/ (<ll>) in nouns and adjectives following it, but not in verbs. Thus in the above examples, cysglyd (an adjective meaning "sleepy") and bachgen (a noun meaning "boy") have been mutated to gysglyd and fachgen, but darllen (a verb meaning "to read") has not been mutated.

From Proto-Brythonic *ɨn, from Proto-Celtic *eni.

• This preposition causes the nasal mutation. Before g and c it becomes yng, before p, b and sometimes m it becomes ym. In some areas the spoken language applies a soft mutation rather than a nasal one to the following word, but in written language the nasal is constant.
• Yn is used with definite nouns. Its equivalent for indefinite nouns is mewn.

• ym (used before m, mh)
• yng (used before ng, ngh)

• mewn

From Old Frisian in, from Proto-Germanic *in, from Proto-Indo-European *en.
