Pronunciation

Etymology

It is from Latin proximus (“nearest, next”), the superlative of prope (“near”),[2][3] with the English suffix -al.[4][5][6][7][3] It is related to proximate and proximity.[8][5][6]

Earliest recorded meaning

Lying very near; immediate: 1727, in P. Longueville's The Hermit.[4][6][5]

Semantic evolution

The general sense "very near, immediate" is now rare.[7][4] The word's main use began in 1803, when John Barclay's New Anatomical Nomenclature used it for the part of a limb nearest the trunk,[4][5] opposed to distal.[6][4][9] It was then extended to anything closer to a centre, axis or point of attachment (1877), and in physiology to the point nearer the source of a flow or impulse.[4] Dentistry uses it from 1872 for the surface of a tooth that faces the next tooth,[4] psychology from 1935 for the stimulus that acts directly on a sense organ,[4] and geology from 1934 for what lies nearer a source of sediment or a volcanic vent.[4][10]
