Welshman having to get out of the shower? (7)
I believe the answer is:
geraint
'welshman having' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'get out of the shower?' is the wordplay.
'out of' means one lot of letters goes inside another (some letters on the outside of others).
'the shower?' becomes 'rain' (rainfall).
'get' placed around 'rain' is 'GERAINT'.
'to' acts as a link.
Can you help me to learn more?
(Another definition for geraint that I've seen is " K".)
