A long wandering tale (7)

I believe the answer is:

odyssey

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

'tale' is the definition.
(I have seen 'long tale' mean 'odyssey' so perhaps 'tale' could also mean 'odyssey')

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for odyssey that I've seen before include "A long adventurous journey - see Homer" , "Homer's epic poem" , "Significant journey (by Homer?)" , "Epic poem - epic voyage" , "Homerian epic" .)

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