(formal) An enormous and devastating fire; the blazing or burning of a large extent or mass of combustible matter, e.g. of a forest, a city, et cetera; inferno. ‘Conflagration’ and ‘blaze’ emphasise rapidness and intenseness of burning, with ‘conflagration’ being an intensification of ‘blaze’ (which itself is of higher intensity than ‘fire’).“Oh, not the fire alarm thing again, Jeeves.”

(of an action, not usually before noun) Characterised by a necessity for a particular purpose; temporarily advantageous, as distinguished from the just or right. Refers strongly to narrow self-interest; the expediency of a thing is a matter of discretion and calculation, and therefore not evidently necessary.
“l think if we were to leave the metropolis for a while it might be expedient, sir.”

(very formal) To strike out, obliterate, rub off, blot out, or mark for deletion (as a word, line, sentence, or a memory). Letters are blotted out, so that they cannot be seen again; they’re expunged, so as to signify that they cannot stand for anything. ‘Expunge’ and ‘obliterate’ refer to forceful and total removal by whatever means, whether by design or not.
“Never mind the poet Burns, Jeeves.”
“No, sir.”
“Expunge the poet Burns from your mind.”
“I have already done so, sir.”

(formal) That which constitutes no necessary or natural part of anything; proceeding from without; irrelevant. The word is considerably general in its implications, but may suggest a difference in kind (‘hard-core facts’ vs. ‘extraneous interpretation’).The inessential element referred to may, if not excluded, be either harmless or detrimental (‘extraneous poisons’, ‘ext. odours’).Omitting the extraneous matter and concentrating on essentials, sir, Mr Gorringe wishes to borrow £1,000 from you.

A mediæval glove, as of flexible fabric, leather, chain mail or plate armour, worn by a knight in armour to protect the hand. In present use, it’s mostly used as part of several idiomatic expressions: to throw down the gauntlet, to pick/take up the gauntlet, to run the gauntlet. The word in the phrase ‘run the gauntlet’ (face one’s punishment) is a corruption of ‘gantlope’; whereas in the former two phrases it comes from the Old French word ‘gantelet’, “glove”.Ok, the gauntlet has been thrown?

[BrE, old-fashioned, informal] An interested glance, especially a flirtatious one, in a way that makes it obvious that one anticipates a romantic relationship or coitus with the person whom they give the glad eye. That expression per se is unlikely to insult anyone in any situation.

(formal, literary) Strictly speaking, a person intoxicated by the action of alcoholic beverages at the moment of being described. As ‘dipsomaniac’, it’s a technical term to designate an excessive drinker, but ‘alcoholic’ has so widely displaced those words that both terms now seem archaic. ‘Dipsomaniac’, once the word for a chronic drink addict, now might be primarily humorous.“My only daughter, for whom l had dreamed of a wonderful golden future, is going to marry an inebriated newt fancier.”

(disapproving) To establish yourself in the favour or good graces of others, especially sb who will be useful to you.
The child took a fancy to the animal, sir. In order to ingratiate herself to the boy’s father, she presented it to him.

[old-fashioned, informal] A ninny or simpleton. The words ‘ninny’ and ‘nincompoop’ have been in the English language for centuries, but are not clearly distinguished from one another. Possibly the former word suggests more of silliness and may be useful in reference to women; the latter word suggests more of obtuseness, dullness, and has particular relevance to describing a foolish man.“Do you know where my husband is?”
“He was here at dinner.”
“I know he was here at dinner, you nincompoop!”

[BrE, old-fashioned, informal] All right, ‘O.K.’
I thought everything was ooja-cum-spiff.

(formal, very strong) Conveying or expressing severe criticism, as language or a speaker; bringing disgrace. It refers to something that not only merits disapproval, but looked on with disdain or scorn. There is often an implication of general rather than merely personal censure involved in anything opprobrious.

“Great Scott, Jeeves! You?”
“The lad made an opprobrious remark about my appearance.”

(adjective, technical) Characterised by pleonasm; using more words than are necessary; superfluous, tautological, redundant. The word can pertain to excessive wordage that results from tautological or surplus expressions or a specific redundant example, and less often to an author or articulator; yet it is more general in referring to a whole style that is wordy or riddled with extraneous expressions, especially when the style is intricate or pompous.Mind you, this definition isn’t pleonastic.

(AmE: baby carriage; BrE old-fashioned: perambulator) A vehicle with four wheels in which a baby can lie down.
“The OED has push bicycle and push cycle as well as push bike, which they label as 'informal.' Myself, I've only heard push bike, but push bicycle is around on the web, as well as push tricycle and push unicycle. Of course, BrE has another push-vehicle, the push-chair, known in AmE as a stroller. Related is the pram, short for perambulator, known in AmE as a baby carriage.”

A difficult or problematic situation about which one doesn’t know what to do. The word originally had no unfavourable connotation, but in modern parlance, when applied to circumstances, it expresses a temporary embarrassed situation conceivably but not necessarily occasioned by an act of one’s own.

“A common enough predicament, sir.”

To walk with a leisurely and careless gait; to stroll, to amble. The word indicates idle, planless going, and may intensify indecisiveness or simply the enjoying of walking. Like ‘amble’, ‘saunter’ refers to an even movement, but emphasises buoyancy of mood as well. One would hardly saunter whilst concerned with unpleasant thoughts, which—combined with the suggestion of a uniform movement—distinguishes the word from ‘stroll’.“Care for a saunter, Angela, old girl?”
“Love to, Bertie, darling.”

(usually before noun, of a person or animal) Trained, having a lot of experience of doing something.“I was young then and not as seasoned as I am now, so I didn’t just tell him that if he thought that then he was an idiot (and an asshole for issuing a challenge, saying, in effect, prove to me that you’re competent) and walk away in search of someone more interesting and pleasant to talk to.” — Arnold Zwicky, http://languagelog.ldc.upenn.edu/nll/?p=2772

(formal, literary) A temporary stay at a place that is not your home; to remain or reside for a brief period of time; to abide, to dwell. The duration of stay implied in these synonymous words is marked by an unambiguous gradation: ‘sojourn’s of longer continuance than ‘abide’, ‘dwell’ comprehends the idea of perpetuity of residence.“So you see l can’t be the chap, if any, who stole Angela from you in Cannes.”
“Cos your affections were engaged elsewhere?”
“During that sojourn.”
“Oh, l see.”

(from Italian, formal) In a subdued or low voice, quietly, privately (of speech).

To speak haltingly, with spasmodic repetitions either because of accidental shyness (anxiety, uncertainty or any excess of emotion) or more commonly because of a physical detect in the organs of utterance. With regards to the degree of the action, ‘stutter’ is a stronger word than ‘stammer’: he who stammers brings forth unintelligible sounds, he who stutters remains speechless for some time.“ … and there was that same, dumb, yearning look in your eyes. Now you stammer out these halting words.”

(Esp of a colour, light or feeling) To spread all over or through sb/sth in the manner of fluid or light.

Devoid of verbal redundancy, smoothly elegant, and pithy; especially in reference to language. The word goes back to a Latin adjective meaning ‘polished’, ‘wiped’, ‘rubbed down’, implying economy of expression as well as elegance. In current use, it emphasises extreme compactness, a strict sticking to the point, and concentrated force.“l shall be very terse about Tuppy, giving it, as my opinion, that in all the essentials, he is more akin to a warthog, than an ex-member of a fine old school.”

(formal) To emit watery vapour; to leak out; to happen. Since the mid-18th century, ‘transpire’ has been used in the sense “leak out, become publicly known,” but although widely used in this sense, ‘transpire' tends to sound stilted and pompous. This usage is considered erroneous by many people.… most people before Cantor would’ve expected that a theoretical account of sets would encompass everything that there was to say about those objects. As we all know, nothing of the sort has transpired.

Turn/twist the knife (in the wound); rub salt into someone's wound. To be more unpleasant than necessary; to increase someone’s distress or embarrassment, e.g. by making constant reminders of the circumstances that caused it.
