constable (n.)youdaoicibaDictYouDict
c. 1200, "chief household officer, justice of the peace," from Old French conestable (12c., Modern French connétable), "steward, governor," principal officer of the Frankish king's household, from Late Latin comes stabuli, literally "count of the stable" (established by Theodosian Code, c.438 C.E.), hence, "chief groom." See count (n.). Second element is from Latin stabulum "stable, standing place" (see stable (n.)). Probably a translation of a Germanic word. Meaning "an officer of the peace" is from c. 1600, transferred to "police officer" 1836. French reborrowed constable 19c. as "English police."
detain (v.)youdaoicibaDictYouDict
early 15c., deteynen, from Old French detenir "to hold off, keep back" (12c.), from Latin detinere "hold off, keep back," from de- "from, away" (see de-) + tenere "to hold" (see tenet). Modern spelling is 17c., from influence of contain, retain, etc. Related: Detained; detaining.
hold (v.)youdaoicibaDictYouDict
Old English haldan (Anglian), healdan (West Saxon), "to contain, grasp; retain; foster, cherish," class VII strong verb (past tense heold, past participle healden), from Proto-Germanic *haldan (cognates: Old Saxon haldan, Old Frisian halda, Old Norse halda, Dutch houden, German halten "to hold," Gothic haldan "to tend"), originally "to keep, tend, watch over" (as cattle), later "to have." Ancestral sense is preserved in behold. The original past participle holden was replaced by held beginning 16c., but survives in some legal jargon and in beholden.

Hold back is 1530s, transitive; 1570s, intransitive; hold off is early 15c., transitive; c. 1600, intransitive; hold out is 1520s as "to stretch forth," 1580s as "to resist pressure." Hold on is early 13c. as "to maintain one's course," 1830 as "to keep one's grip on something," 1846 as an order to wait or stop. To hold (one's) tongue "be silent" is from c. 1300. To hold (one's) own is from early 14c. To hold (someone's) hand "give moral support" is from 1935. Phrase hold your horses "be patient" is from 1844. To have and to hold have been paired alliteratively since at least c. 1200, originally of marriage but also of real estate.
joust (n.)youdaoicibaDictYouDict
c. 1300, from Old French joustes, from joster (see joust (v.)). The sport was popular with Anglo-Norman knights.
These early tournaments were very rough affairs, in every sense, quite unlike the chivalrous contests of later days; the rival parties fought in groups, and it was considered not only fair but commendable to hold off until you saw some of your adversaries getting tired and then to join in the attack on them; the object was not to break a lance in the most approved style, but frankly to disable as many opponents as possible for the sake of obtaining their horses, arms, and ransoms. [L.F. Salzman, "English Life in the Middle Ages," Oxford, 1950]
minstrel (n.)youdaoicibaDictYouDict
early 13c., from Old French menestrel "entertainer, poet, musician; servant, workman; good-for-nothing, rogue," from Medieval Latin ministralis "servant, jester, singer," from Late Latin ministerialem (nominative ministerialis) "imperial household officer, one having an official duty," from ministerialis (adj.) "ministerial," from Latin ministerium (see ministry). The connecting notion is via the jester, etc., as a court position.

Specific sense of "musician" developed in Old French, but in English until 16c. the word was used of anyone (singers, storytellers, jugglers, buffoons) whose profession was to entertain patrons. Only in 18c. was the word limited, in a historical sense, to "medieval singer of heroic or lyric poetry who accompanied himself on a stringed instrument." Reference to blackface music acts in U.S. is from 1843.
