Red-headed, possibly shy Welshman (4)

I believe the answer is:

rhys

I'm a little stuck... Click here to teach me more about this clue!

'welshman' is the definition.
(common Welsh first name)

'red-headed possibly shy' is the wordplay.
'red-headed' becomes 'r' (this might be a standard abbreviation of which I'm unaware).
'possibly' is an anagram indicator.
'shy' is an anagram of 'hys'.
'r'+'hys'='RHYS'

Can you help me to learn more?

(Another definition for rhys that I've seen is " Impetuous Welshman".)

I've seen this clue in the Evening Standard.
