Forms

īnfluentia f (genitive īnfluentiae); first declension[1]

Etymology

It is from Latin īnfluō (“to flow in”), a Medieval Latin noun[2] formed from its present participle īnfluēns with the suffix -ia.[1][3]

Earliest recorded meaning

The MLW finds it first in the Annales Xantenses under the year 873, of a flood of waters in which many people perished with their buildings.[4]

Semantic evolution

The literal sense “inflow” (of water, of light) stayed in use,[2][4] and Du Cange quotes influentiae aquārum for floods as late as 1405.[5] In 13th-century philosophy and theology it became the outflowing power of a higher cause on a lower one: Albert the Great says that what the Arabs call influentia the Greek philosophers call procession.[4] Above all it was the power streaming from the stars on earthly things, and divine influence;[2][6] Petrarch and Boccaccio write of heavenly influentiae.[6] English influence was first an astrological term in the late 14th century, through Old French.[7] In New Latin it also means influenza,[1] a word English borrowed from Italian in 1743.[7]

Timeline

  • 873 – The Annales Xantenses use it of a flood.[4]
  • 1169–1184 – William of Tyre uses it.[3]
  • c. 1240 – Robert Grosseteste writes of higher things pouring their influences on lower ones.[2]
  • 13th century – Albert the Great uses it of the action of a first cause.[4][3]
  • late 14th century – English influence is borrowed through Old French, as an astrological term.[7]
