A poet describing love on a ship? (6)
I believe the answer is:
'on a ship?' is the definition.
(I've seen this before)
'a poet describing love' is the wordplay.
'poet' becomes 'bard' (bard is a kind of poet).
'describing' indicates putting letters inside (describe can mean to form the outline of).
'love' becomes 'o' (In tennis, 'love' means 'zero').
'bard' placed around 'o' is 'board'.
'a'+'board'='ABOARD'
(Other definitions for aboard that I've seen before include "A poet penning nothing on vessel" , "on deck" , "on a yacht maybe" , "on a plane, perhaps" , "On (eg, a ship)" .)
