Entries linking to parenthesize
1540s, "words, clauses, etc. inserted into a sentence, not grammatically connected to it but explaining or qualifying a word," from French parenthèse (15c.) or directly from Medieval Latin parenthesis "addition of a letter to a syllable in a word," from Greek parenthesis, literally "a putting in beside," from parentithenai "put in beside," from para- "beside" (see para- (1)) + en- "in" + tithenai "to put, to place" (from reduplicated form of PIE root *dhe- "to set, put").
By 1715 the sense was extended from the inserted words to the two upright curved brackets (parentheses) used by printers or writers to indicate the words inserted.
Your first figure of tollerable disorder is [Parenthesis] or by an English name the [Insertour] and is when ye will seeme for larger information or some other purpose, to peece or graffe in the middest of your tale an vnnecessary parcell of speach, which neuerthelesse may be thence without any detriment to the rest. [George Puttenham, "The Arte of English Poesie," 1589]
A wooden parenthesis; the pillory. An iron parenthesis; a prison. ["Dictionary of Buckish Slang, University Wit and Pickpocket Eloquence," London, 1811]
word-forming element used to make verbs, Middle English -isen, from Old French -iser/-izer, from Late Latin -izare, from Greek -izein, a verb-forming element denoting the doing of the noun or adjective to which it is attached.
The variation of -ize and -ise began in Old French and Middle English, perhaps aided by a few words (such as surprise, see below) where the ending is French or Latin, not Greek. With the classical revival, English partially reverted to the correct Greek -z- spelling from late 16c. But the 1694 edition of the authoritative French Academy dictionary standardized the spellings as -s-, which influenced English.
In Britain, despite the opposition to it (at least formerly) of OED, Encyclopaedia Britannica, the Times of London, and Fowler, -ise remains dominant. Fowler thinks this is to avoid the difficulty of remembering the short list of common words not from Greek which must be spelled with an -s- (such as advertise, devise, surprise). American English has always favored -ize. The spelling variation involves about 200 English verbs.
