Forms

inséparable (plural inséparables)[1]

Etymology

It is borrowed from Latin īnsēparābilis (“inseparable, indivisible”),[2][3][4] formed from in- (“not”) and sēparābilis (“separable”), which comes from sēparō (“to separate”), itself from sē- (“apart”) and parō (“to arrange”).[4] Rey notes that it was taken over with an eye to séparer, since séparable was not yet in use in French.[5]

Cognate with Old Occitan inseparable, Spanish inseparable and Italian inseparabile.[6]

Earliest recorded meaning

It first meant “indissoluble”, of a marriage, about 1282 in Gauchi's translation of the Gouvernement des princes;[4][5] the TLFi's first record is a later manuscript of the same translation (1444): les mariages doivent estre inseparables “marriages must be indissoluble”.[2]

Semantic evolution

From the marriage bond the word was extended to anything that cannot be separated from something else, in the concrete or the abstract (1545, Bonivard),[2][4][5] and in grammar to elements of language that occur only in compounds (1607, Maupas), such as the prefixes in- and dé-.[2][5][6] In 1656 Pascal applies it to people who never leave each other,[2][5] whence the noun un inséparable (1680), above all in the plural des inséparables (1690).[5]

By 1867 the plural inséparables named small parrots that were believed to live in cages only in pairs, the lovebirds.[2][5][6] The adverb inséparablement is recorded from about 1398.[2]
