Forms

solidifier[1]

Etymology

It is formed from French solide + -ifier.[2][3][1] The Petit Robert adds that it was formed after solidification,[4] which Bloch and Wartburg date to 1572, rare before the 19th century.[5] The adjective was borrowed from Latin solidus (“massive, firm”).[5][6]

Earliest recorded meaning

It first appears in Buffon's mineralogy (1783–1788), as the past participle solidifié “made solid” and as the reflexive se solidifier “to become solid”.[2][7][3]

Semantic evolution

The active verb, “to make solid”, is recorded by Boiste in 1803.[2][7] A figurative use, “to make firm”, followed: the TLFi has it from Lamartine in 1835,[2] and Balzac used se solidifier of things taking on firmness or hardness (1846).[2][8] Rey notes that solidification, an older word, is now felt as a derivative of the verb, especially in its figurative uses.[7]

Timeline

  • 1783–1788 – Buffon uses solidifié and se solidifier.[2][3]
  • 1803 – Boiste records the infinitive.[2][8]
  • 1835 – Lamartine uses it figuratively.[2]
  • 1846 – Balzac uses se solidifier for “to grow firm”.[2][8]
