Yn or Mewn

When to use "yn" vs. "mewn"...


This is my understanding - please correct it if it's wrong!!


You should use yn for specific nouns, and mewn for more general ones. For example you might use "mewn" to say you work in a bank (Dw i'n gweithio mewn banc), but "yn" when you say which specific bank you work in (Dw i'n gweithio yn Natwest). Here are some more examples:


Dw i'n gweithio yn Wrecsam= I work in Wrexham.

Dw i'n gweithio mewn dinas = I work in a city.

Dw i'n gweithio yn y ddinas = I work in the city.


Oedd hi'n dysgu mewn ysgolion lleol - She was teaching in local schools

Oedd hi'n dysgu yn yr ysgol lleol - She was teaching in the local school (THE local school makes it about a specific one)


Wnes i aros mewn gwesty - I stayed in a hotel

Wnes i aros yng Ngwesty'r Ritz - I stayed in the Ritz hotel.


With special thanks to my dictionary, Oxford Pocket Modern Dictionary for help with examples.

Dafydd's explanation is correct. Yn is used with the so called "definite" nouns, and these can be easily grouped as:
- being proceeded by y (e.e. y car)
- a proper name (Caerdydd, Sam)
- a pronoun (me, her)
- a possessive noun (my, her)
