Forms

localiser[1]

Etymology

It is formed from French local + -iser.[2][1][3][4] The adjective local is from Late Latin locālis (“relating to a place”), from locus (“place”).[3]

Earliest recorded meaning

It was created during the Revolution: the TLFi's first record is Roux's French–German dictionary of 1796, with the sense “to put in order, arrange”.[2][5]

Semantic evolution

In 1798 Schwan's dictionary gives it the sense “to make local, adapt”.[2][5][6] A few years later it took its modern meaning, “to place in a given spot by thought” (Destutt de Tracy, 1801), then “to place at a certain date” (Maine de Biran, 1818).[2][5] In medicine Broussais spoke of localizing diseases in 1826,[2][5] and Mozin's dictionary of 1842 has the sense “to confine within limits”.[6][7]

The past participle localisé has been used as an adjective since 1827, as in Hugo's émeute localisée (1862).[2][5] From the verb come localisation (1803) and, much later, the prefixed délocaliser.[5]
