Common Prepositions in Welsh
Prepositions are small but high-impact for accuracy. Learn the common ones with a set phrase each, not only as isolated words.
Core set
• i – to / for (often soft mutation after)
• o – from / of (soft mutation)
• am – about / for (time)
• ar – on
• gyda / efo – with
• yn – in (nasal mutation with yn = in)
Build phrases: i fynd, o Gaerdydd, am dair o’r gloch, ar y bwrdd, gyda ffrind.
Exam habit
When you write a preposition, check the next word’s mutation.
