Forms

părenthĕsis f (genitive părenthĕsis); third declension[1][2] The TLL also records the Greek genitive parentheseos and the spelling parentesis.[3]

Etymology

It is borrowed from Ancient Greek παρένθεσις (parénthesis, “insertion”),[2][1][4][3] literally a putting in beside, from παρα- (para-, “beside”) and ἐν (en, “in”) and a form of the verb for to put.[5]

Earliest recorded meaning

Quintilian and Rutilius Lupus still write it as a Greek word, in Greek letters; as a Latin word it appears from Porphyrio (second half of the 2nd century AD)[4] and Sacerdos on, only in the writers on rhetoric and grammar.[3]

Semantic evolution

In rhetoric it was the figure in which a sentence foreign to the context is put inside another, rendered in Latin as interpositio;[3][2][6] Servius uses it in his commentary on Virgil.[6][3] In grammar it meant the insertion of a letter or syllable into a word, what is now called epenthesis, a sense found in Charisius.[2][1][6]

Bede defines it as a statement inserted into a divided sentence,[7] and medieval writers used the phrase per parenthesin for something said in parenthesis.[7] English parenthesis, from French or directly from Medieval Latin, dates from the 1540s.[5]
