'allow more line' is the definition.
I can't tell whether this defines the answer.

'run out to the fish' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'to the fish' becomes 'eel' (eel is a kind of fish).
'run' is an anagram of 'unr'.
'unr'+'eel'='UNREEL'

'to' acts as a link.

Can you help me to learn more?

(Other definitions for unreel that I've seen before include "sounds amazing" , "Wind like film in a projector" , "Unfurl" , "Take from coil" , "Pull out tape" .)

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