Forms

déploiement m (plural déploiements)[1] Middle French desployement (1538).[2][3]

Etymology

It is formed from French déployer (“to unfold, deploy”) + -ment, from the stem of the verb.[2][3][1] The verb is from Old French desploier, a derivative of ploier (modern ployer), which continues Latin plicō (“to fold”).[4][5] Littré also cites a 16th-century noun desploi of the same meaning, used by D'Aubigné.[6]

Earliest recorded meaning

It is first recorded as desployement in desployement des jambes “stretching out of the legs”, in Robert Estienne's dictionary of 1538, under Latin explicare.[2][7]

Semantic evolution

The noun followed the senses of déployer.[7] From the general sense “action of unfolding, spreading out”, it was used in the army for spreading troops out over a wide front, recorded by the Académie in 1798.[2][7][8] Figuratively it came to mean a large display or show of something (1828, Guizot), recorded by the Académie in 1835.[2][8][7]

The Petit Robert adds the modern sense of putting a new system into service or rolling out software to its users, and notes that the word is often pejorative when it means a show without restraint.[9] The derivative redéploiement, first military, passed into economic language about 1965 for the reorganization of a policy or an industry.[7]
