LONGFELLOW: That's a name we made up back home for people who make foolish designs on paper when they're thinking. It's called doodling. Almost everybody's a doodler. Did you ever see a scratch pad in a telephone booth? People draw the most idiotic pictures when they're thinking. Dr. Von Holler, here, could probably think up a long name for it, because he doodles all the time. ["Mr. Deeds Goes to Town," screenplay by Robert Riskin, 1936; based on "Opera Hat," serialized in "American Magazine" beginning May 1935, by Clarence Aldington Kelland]

necessary (n.)youdaoicibaDictYouDict
mid-14c., "needed, required, or useful things; the necessities of life; actions determined by right or law," perhaps from Old French necessaire (n.) "private parts, genitalia; lavatory," and directly from Latin necessarius (n.), in classical Latin "a relation, relative, kinsman; friend, client, patron;" see necessary (adj.).
private (adj.)youdaoicibaDictYouDict
late 14c., "pertaining or belonging to oneself, not shared, individual; not open to the public;" of a religious rule, "not shared by Christians generally, distinctive; from Latin privatus "set apart, belonging to oneself (not to the state), peculiar, personal," used in contrast to publicus, communis; past participle of privare "to separate, deprive," from privus "one's own, individual," from PIE *prei-wo-, from PIE *prai-, *prei-, from root *per- (1) "forward, through" (see per).

Old English in this sense had syndrig. Private grew popular 17c. as an alternative to common (adj.), which had overtones of condescension. Of persons, "not holding public office," recorded from early 15c. In private "privily" is from 1580s. Related: Privately. Private school is from 1650s. Private parts "the pudenda" is from 1785. Private enterprise first recorded 1797; private property by 1680s; private sector is from 1948. Private eye "private detective" is recorded from 1938, American English.
shame (n.)youdaoicibaDictYouDict
Old English scamu, sceomu "feeling of guilt or disgrace; confusion caused by shame; disgrace, dishonor, insult, loss of esteem or reputation; shameful circumstance, what brings disgrace; modesty; private parts," from Proto-Germanic *skamo (cognates: Old Saxon skama, Old Norse skömm, Swedish skam, Old Frisian scome, Dutch schaamte, Old High German scama, German Scham). The best guess is that this is from PIE *skem-, from *kem- "to cover" (covering oneself being a common expression of shame).

Until modern times English had a productive duplicate form in shand. An Old Norse word for it was kinnroði, literally "cheek-redness," hence, "blush of shame." Greek distinguished shame in the bad sense of "disgrace, dishonor" (aiskhyne) from shame in the good sense of "modesty, bashfulness" (aidos). To put (someone or something) to shame is mid-13c. Shame culture attested by 1947.
shape (n.)youdaoicibaDictYouDict
Old English sceap, gesceap "form; created being, creature; creation; condition; sex, genitalia," from root of shape (v.)). Meaning "contours of the body" is attested from late 14c. Meaning "condition, state" is first recorded 1865, American English. In Middle English, the word in plural also had a sense of "a woman's private parts." Shape-shifter attested from 1820. Out of shape "not in proper shape" is from 1690s. Shapesmith "one who undertakes to improve the form of the body" was used in 1715.
ware (n.)youdaoicibaDictYouDict
"manufactured goods, goods for sale," Old English waru "article of merchandise," also "protection, guard," hence probably originally "object of care, that which is kept in custody," from Proto-Germanic *waro (cognates: Swedish vara, Danish vare, Old Frisian were, Middle Dutch were, Dutch waar, Middle High German, German ware "goods"), from PIE *wer- (4) "to perceive, watch out for" (see ward (n.)). Usually wares, except in compounds such as hardware, earthenware, etc. Lady ware was a jocular 17c. euphemism for "a woman's private parts," and Middle English had ape-ware "deceptive or false ware; tricks" (mid-13c.).
