vocabulary journal

peruse

late 15c., "use up, wear out, go through," from Middle English per- "completely" (see per) + use (v.). Meaning "read carefully" is first recorded 1530s, but this could be a separate formation. Meaning "read casually" is from 19c. Related: Perused; perusing.

desist

mid-15c., from Middle French désister (mid-14c.), from Latin desistere "to stand aside, leave off, cease," from de- "off" (see de-) + sistere "stop, come to a stand" (see assist). Related: Desisted; desisting.

recoil

c. 1300, "retreat," from Old French recul "recoil, backward movement, retreat," from reculer (see recoil (v.)). Meaning "back-kick of a firearm" is from 1570s.

pertinent

late 14c., from Anglo-French purtinaunt (late 13c.), Old French partenant (mid-13c.) and directly from Latin pertinentem (nominative pertinens) "pertaining," present participle of pertinere "to relate, concern" (see pertain). Related: Pertinently.

mastiff

large, powerful breed of dog, early 14c., from Old French mastin "great cur, mastiff" (Modern French mâtin) or Provençal mastis, both from Vulgar Latin *mansuetinus "domesticated, tame," from Latin mansuetus "tame, gentle" (see mansuetude). Probably originally meaning a dog that stays in the house, thus a guard-dog or watchdog. Form in English perhaps influenced by Old French mestif "mongrel."

obsess

c. 1500, "to besiege," from Latin obsessus, past participle of obsidere "watch closely; besiege, occupy; stay, remain, abide" literally "sit opposite to," from ob "against" (see ob-) + sedere "sit" (see sedentary). Of evil spirits, "to haunt," from 1530s. Psychological sense is 20c. Related: Obsessed; obsessing.

doleful

late 13c., with -ful, from Middle English dole "grief" (early 13c.), from Old French doel (Modern French deuil), from Late Latin dolus "grief," from Latin dolere "suffer, grieve," which is of uncertain origin. De Vaan reports that it can be derived from a PIE root *delh- "to chop" "under the assumption that 'pain' was expressed by the feeling of 'being torn apart'. A causative *dolh-eie- 'to make somebody (feel) split' could have become 'to cause pain'. The experiencer must originally have been expressed in the dative." Related: Dolefully.

wan

Old English wann "dark, dusky, lacking luster," later "leaden, pale, gray," of uncertain origin, and not found in other Germanic languages. The connecting notion is colorlessness. Perhaps related to wane. Related: Wanly; wanness.
