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

'paddle' is the definition.
(I've seen this before)

I can't explain the rest of the clue.

(Other definitions for wade that I've seen before include "Walk through water or mud" , "Move through sea" , "British winner of Wimbledon Singles in 1977" , "Walk through water with difficulty" , "Stride through river" .)

I've seen this clue in the Evening Standard.
