Synonym discussion

Sense: adjective/1

While 'high' and 'tall' both describe vertical extent, 'tall' is used for people and narrow objects (a tall tree, a tall man) whereas 'high' describes distance from the ground (a high shelf, a high ceiling). 'Lofty' is a more formal alternative typically applied to impressive architecture or noble ideals (lofty ceilings, lofty ambitions). 'Elevated' suggests something raised above its surroundings, often in a technical or physical sense (elevated platform, elevated blood pressure). When used for prices or costs, 'high' is general (high rent), while 'expensive' describes the item itself rather than the numerical level. For amounts and degrees, 'great' overlaps partially (great importance vs. high importance), but 'great' carries a stronger subjective emphasis.

From Old English 'heah' (tall, lofty, exalted), tracing back through Proto-Germanic *hauha- to the Proto-Indo-European root *keuk- ('to be strong, lifted'). Related to German 'hoch' and Dutch 'hoog'. Figurative senses such as 'important' and 'expensive' emerged during the Middle English period, while the slang meaning for drug intoxication appeared in 1930s America.
