The definite conjugation is easier than the indefinite one. You don’t have to deal with issues the indefinite has.
SUFFIXES:
-(o)m, -(e)m, -(ö)m
-(o)d, -(e)d, -(ö)d
-ja, -i
-juk, -jük
-játok, -itek
-ják, -ik
1st and 2nd PS: you always need a link vowel for simple verbs and for verbs in two consonants, -ít and so on…
And the rest does not require any link vowel. You just attach the 3rd PS, 1st PP, 2nd PP and 3rd PP suffixes to the verb according to vowel harmony.
NOTE! The 3rd PS form has to be conjugated in definite form unlike the indefinite form.
ATTENTION! The ö link vowel only exists in 1st PS and 2nd PS!
