Sailor love Polynesian staple? (4)
I believe the answer is:
taro
'polynesian staple?' is the definition.
(I've seen this in another clue)
'sailor love' is the wordplay.
'sailor' becomes 'tar' (slang term for a sailor).
'love' becomes 'o' (love means zero in tennis).
'tar'+'o'='TARO'
(Other definitions for taro that I've seen before include "Tropical plant with edible tuberous roots" , "Starchy plant" , "Starchy food" , "Shortly pack" , "Fortune-telling cards" .)
