Forms

effectuālis, -e; third declension[1][2]

Etymology

It is formed from Latin effectus + -ālis, from effectus (“accomplishment, result”).[2][1] Etymonline calls it Late Latin;[3] the MLW and Köbler treat it as a medieval word.[2][1]

Earliest recorded meaning

Köbler dates its first record to the 11th century.[1] The MLW's earliest quotation says of a man that his learning grew not by showy knowledge but by unceasing effectualis practice, that is, by learning put into effect.[2]

Semantic evolution

The adjective meant “having effect, efficacious”.[2][4] British writers also used it in law for a plea or act that was valid, and as a noun for a valid plea; in scholastic philosophy it described what happens by way of effect, as opposed to cause.[4] In the MLW its adverb effectualiter means “in practice, in the carrying out”.[2]

Hungarian charters use it of a real, actual execution of an order, and in law of a final term that allows no further delay;[5] Polish texts from the 15th and 16th centuries have it in the sense “real, actual”.[6] Old French took it over as effectuel, the source of English effectual.[3]

Timeline

  • 11th century – First recorded, according to Köbler.[1]
  • late 14th century – English borrows effectual through Old French.[3]
  • 1402 – A Hungarian charter speaks of the effectualis executio of a royal mandate.[5]
  • 1414 – A British document uses it of business that would have real effect.[4]
  • 1429 – A Polish record speaks of the actual possession of goods.[6]
