Jib, perhaps, as Lisa may do (4)

Ross

I believe the answer is:

sail

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

'jib perhaps' is the definition.
(jib is a kind of sail)

'lisa may do' is the wordplay.
'lisa' anagrams to 'SAIL'.
But, I'm not clear how this is indicated.

'as' acts as a link.

Can you help me to learn more?

(Other definitions for sail that I've seen before include "Travel on water propelled by wind" , "It catches the wind on a mast" , "Begin a voyage" , "project" , "Canvas on board" .)
