indispensable

Pronunciation

• /ˌɪndɪˈspɛnsəbəl/^[1]

Etymology

It is borrowed from Medieval Latin indispēnsābilis (“not subject to dispensation”),^{[2][3][4][5][6]} also spelled indispēnsībilis,^[7] formed from in- (“not”) and dispēnsābilis,^[2][6][4] from Latin dispēnsō (“to pay out, distribute by weight, administer”), a frequentative of dispendō (“to pay out”), from dis- (“out”) and pendō (“to hang; weigh; pay”).^[3][8] The OED compares French indispensable, recorded in the 17th century,^[2] and Merriam-Webster treats the word as an English formation, dispensable with a negative prefix.^[9]

Earliest recorded meaning

In church law, not subject to dispensation; that cannot be allowed by suspending a law or canon: before 1556, in a letter of Cranmer.^[2][10][4] Etymonline dates the word to the 1530s,^[3] and Dictionary.com to 1525–35.^[5]

Semantic evolution

The ecclesiastical sense died out by about 1650.^[2][7] In 1653 More used the word of a law, duty or obligation that cannot be set aside or neglected.^[2][9] From 1696, in Phillips's New World of Words, it meant "that cannot be done without; absolutely necessary", now the main sense.^[2][3] Johnson (1755) defined it as "not to be remitted; not to be spared; necessary".^[11] The noun, an indispensable person or thing, is recorded from 1681.^[2] In the early 19th century it named a small bag that women carried instead of a pocket, after French use (1800–06),^[2][3] and in the plural it was a jocular euphemism for trousers (from before 1828), like inexpressibles.^[2][3][9]
