skeletal

Etymology

It is formed from English skeleton + -al,^[2][3][1][4] with the suffix added to the stem of the noun.^[5][6] Skeleton is from New Latin sceleton,^[5][2] from Ancient Greek σκελετόν (skeletón), short for the phrase with σῶμα (sôma, “body”), dried-up body,^[5][2][7] the neuter of σκελετός (skeletós, “dried up”),^[5][2] from σκέλλω (skéllō, “to dry up”).^[5][2][7] Etymonline connects the Greek verb with Proto-Indo-European *skele- (“to parch, wither”), the root of sclero-.^[2]

Earliest recorded meaning

Of or belonging to, forming or resembling a skeleton: 1854, in R. Owen's work on the structure of the skeleton and teeth.^[5][6] Etymonline dates it to 1849,^[2] Dictionary.com to 1850–55.^[4]

Semantic evolution

In physiology a skeletal muscle, attached to and moving part of the skeleton and mostly under voluntary control, is recorded from 1877,^[5] and in soil science a skeletal soil, a thin stony one, from 1932.^[5] Two figurative uses came only in the 20th century: suggestive of a skeleton through extreme thinness, emaciated (1952),^[5][3] and consisting only of a framework or outline, bare (1961).^[5][6]
