A / Ac - And

  • When to use 'a' or 'ac' for 'and' in Welsh?

    There are two forms of the word 'and' in Welsh. They do not differ in meaning. The two forms are:-



    Use ‘a’ when the next word starts with a consonant.

    Brawd a chwaer - brother and sister

    Dydd a nos - day and night

    Use ‘ac’ when the next word starts with a vowel. The Welsh vowels are:- a, e, i, o, u, w, y

    Misoedd ac wythnosau - months and weeks

    Banana ac afal - banana and apple

    Some Welsh words use 'a' before them and not 'ac' even though they start with a consonant. We have not listed the exceptions to the above rule here as it is probably easier to acquaint yourself with them as you go along.
