Intrigue sailor, first to sail globe (6)
I believe the answer is:
absorb
'intrigue' is the definition.
(thesaurus)
'sailor first to sail globe' is the wordplay.
'sailor' becomes 'ab' (abbreviation for able seaman).
'first to' says to take the initial letters.
'globe' becomes 'orb' (synonyms).
The initial letter of 'sail' is 's'.
'ab'+'s'+'orb'='ABSORB'
(Other definitions for absorb that I've seen before include "hold" , "Carved figure" , "Grip" , "Occupy the mind fully as good book will" , "Assimilate or take in as a sponge" .)
