Writer welcomes first editor from Dublin of returning Welsh arts festival (10)
I believe the answer is:
eisteddfod
'welsh arts festival' is the definition.
(I've seen this before)
'writer welcomes first editor from dublin of returning' is the wordplay.
I cannot really see how this works, but
'writer' could be 'ed' (I've seen this in other clues) and 'ed' is present in the answer.
'first' could be 'ist' (ist resembles 1st) and 'ist' is found within the answer.
'editor' could be 'ed' and 'ed' is present in the answer.
'from' could be 'o' (I've seen this in other clues) and 'o' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for eisteddfod that I've seen before include "Celtic festival" , "Welsh cultural festival" , "Welsh festival of music and poetry" , "Welsh art festival" , "arts competition" .)
