Each Other: Ei Gilydd

Level 4

Ei gilydd means "each other". The first word changes to match who is involved: ei gilydd (they), ein gilydd (we), eich gilydd (you).

How It Works

Matching the person

  • they: Maen nhw'n caru ei gilydd. — They love each other.
  • we: Dyn ni'n gweld ein gilydd bob wythnos. — We see each other every week. (North: Dan ni'n gweld ein gilydd)
  • you (plural): Dych chi'n nabod eich gilydd? — Do you know each other?

With prepositions the preposition comes first, and short forms appear after a vowel (see Short Possessives):

  • Maen nhw'n siarad â'i gilydd. — They talk to each other.
  • Maen nhw'n debyg i'w gilydd. — They look like each other.
  • Maen nhw'n ysgrifennu at ei gilydd. — They write to each other.

"Together": gyda'i gilydd (they), gyda'n gilydd (we), gyda'ch gilydd (you). The North also says efo'i gilydd, efo'n gilydd (see gyda and efo).

Handy phrases: o bryd i'w gilydd — from time to time; at ei gilydd — altogether, on the whole.

Common Mistakes

  • Using eu for "they".

    Maen nhw'n caru eu gilydd.
    Maen nhw'n caru ei gilydd.

    For "they", the fixed phrase is ei gilydd, even though "their" is usually eu.

  • Not matching "we".

    Dyn ni'n gweld ei gilydd bob wythnos.
    Dyn ni'n gweld ein gilydd bob wythnos.

    The first word matches the people involved: ein gilydd for ni, eich gilydd for chi.
