Bydd ansoddeiriau ac enwau'n treiglo'n feddal ar ôl 'yn traethiadol':
Dych chi’n dda. (da – good – adjective – soft mutation)
Dych chi’n berson da. (person – person – noun – soft mutation)
Fydd berfenwau ddim yn treiglo ar ôl 'yn traethiadol':
Dych chi’n cwyno gormod (cwyno – verb – to complain – no mutation)
Adjectives and nouns take a soft mutation after ‘yn’:
Dych chi’n dda. (da - good - adjective - soft mutation)

Verbs do not mutate after ‘yn’:
Dych chi’n cwyno gormod (cwyno – verb - to complain - no mutation)
Os na fyddwch chi'n siŵr ai ansoddair yw gair neu beidio, gofynnwch y cwestiwn:
Sut fath o berson yw e / hi?
Os byddwch chi'n gallu dweud y gair fel ateb i'r cwestiwn hwn, wedyn andoddair ydy, e.e:
creadigol – Pa fath o berson yw e? – Mae e’n greadigol
creative – What sort of person is he? – He is creative
If you are unsure whether a word is an adjective or not, ask the question:
What sort of person is he/she?
If this question can be answered with the word it’s an adjective, e.g:
creadigol - Pa fath o berson yw e? - Mae e’n greadigol
creative - What sort of person is he? - He is creative
