From Late Latin parenthesis (“addition of a letter to a syllable in a word”), from Ancient Greek παρένθεσις (parénthesis), from παρεντίθημι (parentíthēmi, “I put in beside, mix up”), from παρά (pará, “beside”) + ἐν (en, “in”) + τίθημι (títhēmi, “put, place”), from Proto-Indo-European *dʰeh₁- (“to put, to do”).

- Either of a pair of brackets, especially round brackets, ( and ) (used to enclose parenthetical material in a text).
- 1824, John Johnson, Typographia, Or the Printer's Instructor, London: Longman, Hurst, Rees, Orme, Brown and Green:
- There be five manner of points and divisions most used among cunning men; the which if they be well used, make the sentence very light and easy to be understood, both to the reader and hearer: and they be these, virgil,—come,—parenthesis,—plain point,—interrogative […] it is a slender stroke leaning forward, betokening a little short rest, without any perfectness yet of sentence.
