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

'welshman' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'regularly call funny' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'call'+'funny'='callfunny'
The alternate letters of 'callfunny' are 'ALUN'.

Can you help me to learn more?
