Now that you can talk about your morning routine in the present tense here's how to use the past tense.

Notice that what we're doing is adding a personal ending to something called the stem of the verb. How do we find the stem?

If the verb ends with a vowel we drop the vowel

(In Welsh the vowels are a e i o u w y)

gwisgo gwisgais i

If the verb ends with -io we drop the o.

ffonio (to telephone) ffoniais i

If the verb ends in -ed / -eg we drop the end.

cerdded (to walk) cerddais i
rhedeg (to run) rhedais i
also - gweld (to see) gwelais
