'plenty of room' is the definition.
'oceans' can be an answer for 'plenty' (thesaurus). I'm unsure of the 'of room' bit.

'to manoeuvre' indicates anagramming the letters.
'canoes' anagrammed gives 'OCEANS'.

'for' acts as a link.

Can you help me to learn more?

(Other definitions for oceans that I've seen before include "Great seas" , "Atlantic, Pacific etc" , "expanses?" , "Large amounts (of water)" , "Southern Indian" .)
