Synonym discussion

Sense: verb/1

All four verbs describe putting something into soil so that it grows, but each fits a different stage. 'Plant' is the everyday choice and works for almost anything you push into the ground — a seed, a bulb, a sapling, or a fully grown tree being moved. 'Sow' is narrower and is used mainly for scattering seeds across a wide area, especially grain or grass; you sow wheat, but you plant a tree. 'Transplant' specifically means moving an already-growing plant from one spot to another — a tomato seedling from a tray into the garden, or a tree from one yard to a new one. 'Cultivate' is the broadest of all: it covers preparing the soil, planting, watering, weeding, and caring for the crop right through to harvest. So a farmer might cultivate a hectare of land on which she has sown rice and planted a few fruit trees, then transplanted the strongest seedlings into a new row.

Prepositions

Etymology

LatinOld EnglishOld FrenchMiddle EnglishModern English

From the Latin noun 'planta', meaning the sole of the foot or a young shoot pressed into the ground with the foot. The word entered Old English as 'plante' for a young growing thing, then came back into Middle English with extra meanings borrowed from Old French 'plante'. The 'factory' and 'machinery' meanings developed much later, in the 18th and 19th centuries, when industrial English began describing the equipment that was 'planted' or set up at a worksite. The 'frame someone' and 'spy' senses are 19th- and 20th-century slang extensions of the basic idea of putting something or someone in a hidden place.
