Account about Israeli port (4)
I believe the answer is:
acre
'israeli port' is the definition.
(port in Israel)
'account about' is the wordplay.
'account' becomes 'ac' (abbreviation for account).
'about' becomes 're' ('re' means regarding or about).
'ac'+'re'='ACRE'
(Other definitions for acre that I've seen before include "Unit of land measurement" , "amount of land" , "marine location in Israel" , "Levant sea port" , "Unit of area of 4,840 square yards" .)
