periphrastic adjective the periphrastic nature of legal syntax: circumlocutory, circuitous, roundabout, indirect, tautological, pleonastic, prolix, verbose, wordy, long-winded, rambling, wandering, tortuous, diffuse. WORD NOTE periphrastic A friend used to collect what he called middle-class circumlocutions —unnecessarily elongated phrases that English suburban bores once liked to employ to give them a friendlier, breezier tone than that for which they were normally known. So instead of asking for beer in the pub — A pint of the amber fluid, my man! Instead of calling for the bill —What's the damage, old boy? . Rather than referring to my wife —please meet the little woman, or my better half. May I smoke in your house? Of course, dear fellow — it's Liberty Hall here. And this being Britain there were many self-deprecating versions of the form: of a brand-new car parked proudly on the gravel at the golf club — Oh yes, not a bad little bus, gets you from A to B. The term circumlocution for such a roundabout construction is a fair choice, of course; but technically the term in grammar is periphrasis (which merely derives from the Greek, while circumlocution is from the Latin ), and periphrastic, so pleasantly complicated-sounding a word, is the adjective. It is vaguely similar in its sound, of course, to paraphrase —and since that word means "to expand in order to make clear, " while periphrase in essence means "to expand in order to make slightly ridiculous, " the close similarity in both sound and sense will serve to ensure that both uses are carefully chosen. Or so one hopes. — SW Conversational, opinionated, and idiomatic, these Word Notes are an opportunity to see a working writer's perspective on a particular word or usage.
