sycamore (n.) Look up sycamore at Dictionary.com
mid-14c., from Old French sicamor, from Latin sycomorus, from Greek sykomoros, from sykon "fig" + moron "mulberry." Or perhaps a folk-etymology for Hebrew shiqmah "mulberry." A Biblical word, originally used for a species of fig tree (Ficus sycomorus) common in Egypt, Syria, etc., whose leaves somewhat resemble those of the mulberry; applied from 1580s to Acer pseudoplatanus, a large species of European maple, and from 1814 to the North American shade tree that is also called buttonwood (Platanus occidentalis, introduced to Europe from Virginia 1637 by Filius Tradescant). Some writers have used the more Hellenic sycomore in reference to the Biblical tree for the sake of clarity.
