I believe the answer is:

protean

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

'though versatile' is the definition.
'protean' can be an answer for 'versatile' (thesaurus). I'm not sure about the 'though' bit.

'only one part' is the wordplay.
'one part' can be anagrammed to 'PROTEAN'.
But, I'm not clear how the anagram is indicated.

'takes' acts as a link.

Can you help me to learn more?

(Other definitions for protean that I've seen before include "having many variations" , "Taking on different forms" , "Taking many shapes" .)

I've seen this clue in The Globe and Mail.
