From the same root
Forms
prōlongō (present infinitive prōlongāre, perfect active prōlongāvī, supine prōlongātum); first conjugation[1]
Etymology
It is formed from Latin prō- + longus (“long”).[2][3][4][5] The TLL compares ēlongō.[6]
Earliest recorded meaning
The TLL finds it first in the Old Latin Bible, in Isaiah's “lengthen your cords” as quoted by Augustine.[6] Hilary of Poitiers has peccata prolongans (“drawing out sins”) in his commentary on Psalm 128.[6][7]
Semantic evolution
It meant to make something longer in space or further off, and above all to prolong in time: the Psalms speak of a sojourn prolonged, the Vulgate of days prolonged, and Augustine in the Confessions of memory lengthening as he sings.[6][2][3] Lewis and Short call it a Late Latin word used for prōrogō and prōferō.[2] In Medieval Latin it also meant to remove or banish, to move away, and to delay or put off,[8][9] and grammarians used it for lengthening a syllable.[10] English prolong (early 15th century) comes from Old French and directly from Late Latin, and purloin comes from the Anglo-French form of the same elements.[5]
