The pronoun comes in two parts in Welsh and the first part shouldn't be omitted e.g.

fy nghadw i	to keep me
dy weld di	to see you

Welsh pronouns are followed by the following mutations:

	Mutation
fy	nasal	cerdd > fy ngherddi
dy	soft	barn > dy farn di
ei (gwr.)	soft	drama > ei ddrama e/o
ei (ben.)	aspirate	tro > ei thro hi
ein	-	barn > ein barn ni
eich	-	cerdd > eich cerdd chi
eu	-	drama > eu drama nhw

NB

The aspirate h is placed in front of a vowel at the beginning of nouns and verb-nouns after ei or 'i (her), ein or 'n and eu or 'u, e.g.

ei hysgol hi

ein harwain ni.
