There are two
ways of saying 'ought to' or 'should' in Welsh, using 'dylwn'
(south) and 'dylswn' (north). Neither are wrong, but it's
best to be aware of both, and let local usage dictate which
one you use. As the northern variation is simply the same
as the southern, but with an s following the l,
only dylwn is listed here. Do not use 'yn'.
"I ought to",
"Ought I?", "Should I?"
"I ought not", "I shouldn't"
