Good words to have

 Adjure 
uh-JOOR 
1: to command solemnly under or as if under oath or penalty of a curse
2: to urge or advise earnestly
Adjure and its synonyms entreat, importune, and implore all mean "to ask earnestly." Adjure implies advising as well as pleading, and is often accompanied by the invocation of something sacred ("in God's name, I adjure you to cease"). Entreat implies an effort to persuade or overcome resistance ("he gently entreated her to stay"). Importune goes further, adding a sense of annoying persistence in trying to break down resistance to a request ("importuning viewers for contributions"). Implore, on the other hand, suggests a great urgency or anguished appeal on the part of the speaker ("she implored the king to have mercy")


Billet-doux 
bill-ee-DOO 
A love letter
The first recorded use of the French word billet doux (literally, "sweet letter") in an English context occurs in John Dryden's 1673 play Marriage a-la-Mode.

Weltanschauung 
 VELT-ahn-show-ung ("ow" as in "cow") 
(Often capitalized Weltanschauung) a comprehensive conception or apprehension of the world especially from a specific standpoint
The German word Weltanschauung literally means "world view"; it combines Welt ("world") with Anschauung ("view"), which ultimately derives from the Middle High German verb schouwen ("to look at" or "to see"). When we first adopted it from German in the mid-19th century, weltanschauung referred to a philosophical view or apprehension of the universe, and this sense is still the most widely used. It can also describe a more general ideology or philosophy of life.

Ragtag 
RAG-tag 
1: ragged, unkempt
 2: composed of diverse often incongruous elements: motley
Tag and rag was a relatively common expression in the 16th and 17th centuries, and it was often used pejoratively to refer to members of the lower classes of society. By the 18th century, the phrase had been expanded to ragtag and bobtail. That expression could mean either "the lower classes" or "the entire lot of something" (as opposed to just the more desirable parts—the entire unit of an army, for example, not just its more capable soldiers). Something described as ragtag and bobtail, then, was usually common and unspectacular. Ragtag and bobtail was eventually shortened to ragtag, the adjective we know today, which can describe an odd mixture that is often hastily assembled or second-rate


Struwwelpeter
STROO-uhl-pee-tuhr 
A person with long, thick, disheveled hair.
From Struwwelpeter, the title character of the 1845 children’s book Der Struwwelpeter (Shockheaded Peter) by Heinrich Hoffman. Earliest documented use: 1909.

Peradventure 
PER-ud-ven-cher 
1: doubt
2: the possibility of a particular outcome in an uncertain situation : chance
 When Middle English speakers borrowed par aventure from Anglo-French (in which language it means, literally, "by chance"), it was as an adverb meaning "perhaps" or "possibly." Before long, the word was anglicized to peradventure, and turned into a noun as well.

Carceral 
 KAHR-suh-rul 
of, relating to, or suggesting a jail or prison
Our earliest known evidence of carceral—an adjective borrowed directly from Late Latin—dates to the late 16th century, with evidence of incarcerate ("to imprison") appearing shortly thereafter; they're both ultimately from carcer, Latin for "prison." The English verb cancel is also linked to carcer via Latin cancelli, a word meaning "lattice" that likely developed from an alteration of carcer. Carceral is a word that is generally not found outside the confines of academic or legal contexts.

Bovarism
BO-vuh-riz-em 
A romanticized, unrealistic view of oneself.
From Emma Bovary, the title character in Gustave Flaubert’s 1857 novel Madame Bovary. Earliest documented use: 1902.


Nexus 
NEK-sus 
1: connection, link; also : a causal link
2: a connected group or series
3: center, focus
The word comes from nectere, a Latin verb meaning "to bind." A number of other English words are related to nectere. The most obvious is connect, but annex (meaning "to attach as an addition," or more specifically "to incorporate into a political domain") is related as well. When nexus came into English in the 17th century, it meant "connection." Eventually, it took on the additional meaning "connected series" (as in "a nexus of relationships"). In the past few decades it has taken a third meaning: "center" (as in "the trade nexus of the region"), perhaps from the notion that a point in the center of an arrangement serves to join together the objects that surround it.


Gnathonic
na-THON-ik 
Sycophantic.
From Gnatho, a sycophant in the comedy Eunuchus (The Eunuch) by the Roman playwright Terence, written in 161 BCE. The name is coined from the Greek word gnathos (jaw). The subject of Gnatho’s flattery, Thraso, has also given a word to the English language: thrasonical. Earliest documented use: 1637.


Luculent 
LOO-kyuh-lunt 
clear in thought or expression
The Latin noun lux, meaning "light." The English word first appeared in the 15th century with the meaning "brilliant" or "shining," as in "a luculent flame." By the mid-16th century, the "clear in thought or expression" sense had begun to shine, and by that century's end another sense was flickering with the meaning "illustrious" or "resplendent," as in Ben Jonson's 1599 description of a "most debonair and luculent lady." Both the "illustrious" and the "emitting light" senses have fallen out of use, and even the "clear" sense is now rare. Today's writers seem to prefer another lux descendant with a similar meaning: lucid.
