plant: [OE] Etymologically, a plant is probably something you press into the ground with the ‘sole’ of your foot. The word was borrowed from Latin planta ‘shoot, sprout, cutting’, a derivative of the verb plantāre ‘plant, transplant’, and it has been speculated that this was based on Latin planta ‘sole of the foot’ (source of English plantain and plantigrade ‘walking on the soles of the feet’ [19]).

plant (n.)youdaoicibaDictYouDict
Old English plante "young tree or shrub, herb newly planted," from Latin planta "sprout, shoot, cutting" (source of Spanish planta, French plante), perhaps from *plantare "to drive in with the feet, push into the ground with the feet," from planta "sole of the foot," from nasalized form of PIE *plat- "to spread, flat" (see place (n.)).

Broader sense of "any vegetable life, vegetation generally" is first recorded 1550s. Most extended usages are from the verb, on the notion of "something planted;" such as "construction for an industrial process," 1789, at first with reference to the set-up of machinery, later also the building; also slang meaning "a spy" (1812). Many of these follow similar developments in the French form of the word. German Pflanz, Irish cland, Welsh plant are from Latin.
