sycamore (n.)
mid-14c., sicamour "mulberry-leaved fig tree," from Old French sicamor, sagremore, from Latin sycomorus, from Greek sykomoros "African fig-tree," literally "fig-mulberry," from sykon "fig" (see fig) + moron (see mulberry). But according to many sources this is more likely a folk-etymology of Hebrew shiqmah "mulberry."

A Biblical word, originally used for a wide-spreading shade tree with fig-like fruit (Ficus sycomorus) common in Egypt, Palestine, Syria, etc., whose leaves somewhat resemble those of the mulberry; applied in English from 1580s to a large species of European maple (also plane-tree), perhaps because both it and the Biblical tree were notable for their shadiness (the Holy Family took refuge under a sycamore on the flight to Egypt), and from 1814 to the North American shade tree that also is called a buttonwood, which was introduced to Europe from Virginia 1637 by John Tradescant the Younger).

Spelling apparently influenced by sycamine "black mulberry tree," which is from Greek sykcaminos, which also is mentioned in the Bible (Luke xvii.6). For the sake of clarity, some writers have used the more Hellenic sycomore in reference to the Biblical tree.

"quality or condition of being flat or level," 1650s, from plane (adj.) + -ness.

plantain (n.1)

"tropical banana-like tree or fruit," 1550s, plantan, from Spanish plátano, plántano, probably from Carib palatana "banana" (Arawak pratane), and altered by association with Spanish plátano "plane tree," from Medieval Latin plantanus "plane tree," itself altered (by association with Latin planta "plant") from Latin platanus (see plane (n.4)). So called from the shape of its leaves. There is no similarity or relation between this plant and plantain (n.2).

biplane (n.)
"airplane with two full wings, one above the other," 1874 as a theoretical notion; first attested 1908 in reference to the real thing; from bi- "two" + plane (n.1). So called from the two "planes" of the double wings. Earlier it was a term in mathematics (1870).
explain (v.)

early 15c., explanen, "make (something) clear in the mind, to make intelligible," from Latin explanare "to explain, make clear, make plain," literally "make level, flatten," from ex "out" (see ex-) + planus "flat" (from PIE root *pele- (2) "flat; to spread").

The spelling was altered by influence of plain. Also see plane (v.2). In 17c., occasionally used more literally, of the unfolding of material things: Evelyn has buds that "explain into leaves" ["Sylva, or, A discourse of forest-trees, and the propagation of timber in His Majesties dominions," 1664]. Related: Explained; explaining; explains. To explain (something) away "to deprive of significance by explanation, nullify or get rid of the apparent import of," generally with an adverse implication, is from 1709.
