immerse

Etymology

It is borrowed from Latin immersus (“dipped, plunged in”), the past participle of immergō (“to plunge in, dip into”),^{[2][3][4][5][6]} which is formed from in- (“in”) and mergō (“to dip, plunge”).^[2][7][5][4] The participle had already been taken into Middle English as immersed.^[8][7][2] The base verb is probably from Proto-Indo-European *mezgo- (“to dip, to sink”),^[3] and it is also the source of merge, emerge and submerge.^[9]

Earliest recorded meaning

Stuck right in, deeply embedded: the participle immersed is used of an arrow in a Middle English translation of Chauliac's Grande Chirurgie, probably before 1425.^[8][2] The verb proper is first recorded in 1605, in Bacon's Advancement of Learning,^[6][2] and Merriam-Webster Unabridged dates its first use to the 15th century.^[4]

Semantic evolution

The figurative use came first in the record: Bacon's verb of 1605 means to cause to enter, involve or merge, a sense the OED follows until 1734.^[6] The literal sense of dipping or plunging into a liquid, with baptism as a special case, is recorded from 1613 in Cawdrey's Table Alphabeticall.^[6] From the 1660s the verb was applied to absorption in study, work or passion,^[3][6] and this has remained the common figurative sense, usually in the passive or reflexive.^[10] Johnson (1755) gave three senses: to put under water, to sink or cover deep, and to keep in a state of intellectual depression.^[11] The derivative immersive was later applied to computer systems whose three-dimensional image seems to surround the user.^[10]
