Terrible puns twisted into yarns (4)

I believe the answer is:

spun

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

'twisted into yarns' is the definition.
I can't tell whether this definition defines the answer.

'terrible puns' is the wordplay.
'terrible' indicates anagramming the letters.
'puns' with letters rearranged gives 'SPUN'.

Can you help me to learn more?

(Other definitions for spun that I've seen before include "Rapidly rotated" , "Drawn out and twisted (like yarn)" , "Twirled" , "Was web" , "Turned round quickly" .)

I've seen this clue in The Irish Times.
