Usage notes

In the colloquial language, the preterite of this verb is almost never used; the past tense is rendered by means of the periphrastic imperfect, e.g. oedd o ’n medru ‎(“he could, he was able to”).
In the colloquial language, the future tense of this verb has a present-tense meaning as well, so medra i means both ‘I can’ and ‘I will be able to’.

Synonyms

(be able to): gallu
(know): adnabod

Antonyms

ffili ‎(“fail, be unable, cannot”)
methu ‎(“fail, be unable, cannot”)
