Circa 1350, from Old French sicamor, from Latin sycomorus, from Ancient Greek συκόμορος (sukomoros, “fig-mulberry”), from σῦκον (sukon, “fig”) + μόρον (moron, “mulberry”). Possibly influenced by Hebrew שִׁקְמָה (shikmá, “mulberry”).
sycomore (plural sycomores)
Usage notes 
Sycomore is an obsolete spelling of sycamore that hearkens closer to the word's Greek roots. Some writers have used the more Hellenic sycomore when referring to the Biblical tree to distinguish it from other trees now called sycamore.
