Welsh/Grammar/Prepositions

Prepositions that cause SM

The following prepositions cause a soft mutation. They can be easily memorised in this digestible order:

• Dwi'n siarad am 'raglenni teledu.
• Mae ef ar dŷ rhywun.
• Ydych chi dan fwrdd?
• Maen nhw'n chwarae dros Gymru.
• Croeso i Gaerdydd!
• Dwi'n dod o Gaernarfon.
• Dywedwch wrth bobl am y ffaith.
• Mae'r cerdyn hwn gan bawb.

Personal Forms

Prepositions in Welsh, unlike many other European languages, may have personal forms for each pronoun. For example, the preposition 'ar' (on) must become 'arna i' for (on me).

Mewn v. Yn

Mewn is used for indefinite situations. Yn is used for definite situations. Generally, mewn can be translated as in a.

e.g Dwi'n mynd mewn awyren

I'm going in an aeroplane

Wnes i brawf cemeg yn yr ysgol heddiw

I did a chemistry test in [the] school today
