Only Noel can make it (4)

I believe the answer is:

lone

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

'only' is the definition.
(synonyms)

'noel can make it' is the wordplay.
'noel' anagrams to 'LONE'.
However, I'm unsure how this is indicated.

Can you help me to learn more?

(Other definitions for lone that I've seen before include "Sole" , "Solitary or single" , "Companionless" , "Unaccompanied" , "He likes to operate by himself" .)
