doxology
Origin
From Medieval Latin doxologia, from Ancient Greek δοξολογία (doxología, “a praising”), from δοξολόγος (doxológos, “giving or uttering praise”), from δόξα (dóxa, “glory, honor, repute”), from δοκέω (dokéō, “to think, expect”).
douth
Origin
From Middle English douthe, douth, duweðe (“body of retainers, people, might, dignity, worth”), from Old English duguþ (“manhood, host, multitude, troops”), from Proto-West Germanic *dugunþu, *dugunþi, from Proto-Germanic *dugunþō (“power, competency, notefulness, virtue”), from *duganą (“to be useful”), from Proto-Indo-European *dʰewgʰ- (“to be ready, be sufficient”). Cognate with North Frisian døgd, døged (“ability, good deed”), Dutch deugd (“virtue”), German Tugend (“virtue”), Swedish dygd (“virtue”), Danish dyd (“virtue”), Icelandic dygð, dyggð (“virtue”). Related to dow, doughty.
doldrum
Origin
The noun is possibly derived from dull or Middle English dold (past participle of dullen, dollen (“to make or become blunt or dull; to make or become dull-witted or stupid; to make or become inactive”), from dul, dol, dolle (“not sharp, blunt, dull; not quick-witted, stupid; lethargic, sluggish”); see further at dull), modelled after tantrum. The adjective is probably derived from the noun.
