I like seeing how this verb uses the reflexive "ym" to change "deol" (expulsion) into ymddeol, (retirement)!
As in to quit work in one's old age or to go to bed?
I've only ever seen it used to mean "To stop working" and from what I get from Geiriadur Prifysgol Cymru that is the only use for it.
Could there not be some consistency applied to whether 'to' is required in front of verbs? Diolch.
There should be. Verbnouns (the dictionary form in Welsh) in isolation are translated either as 'To X' or as 'Xing'.
My dictionary, Collins-Spurrell, also gives "to resign".
ymddiswyddo - resigning, to resign
Diolch, dictionary is a 1977 edition, guess out of date by now.
A reply for BruceF, really - more joy in seeing the component parts of ymddiswyddo! Diolch, ibisc.
