Pronunciation

  • IPA: /kənˈsɪs.tənt/[1]

Etymology

It is borrowed from Latin cōnsistentem, the present participle of cōnsistere “to stand firm, take a position, stop”,[2][3][4] from con- “together” and sistere “to place”,[2] a causative of stāre “to stand”,[2] from Proto-Indo-European *sta- (“to stand”).[2] It is related to consist and consistency.[4][2]

Earliest recorded meaning

Consisting or composed of, a sense now obsolete: the 1570s in Etymonline, 1578 in the OED.[2][5] Consistent age, the age when growth has stopped, is from 1574.[5]

Semantic evolution

Standing still or firm is from 1604,[5] remaining in the same state from 1647,[5] and of a material, holding together, firm, from 1647, a physical sense that survives in consistency.[5][2] Standing together in agreement, compatible, is from the 1640s (1646 in the OED), and 1638 in MWU;[2][5][3] being in agreement with itself, coherent, is from 1651,[5] and marked by consistency, steady, from 1732.[2]
