" obscure "

[Adjective]  | "ob*scure" | \ äb-ˈskyu̇r \

1: dark, dim

2: shrouded in or hidden by darkness

3: not clearly seen or easily distinguished : faint

Origin: 15th century ;

 Middle English, "dark, unenlightened, incomprehensible," borrowed from Anglo-French & Latin; Anglo-French oscur, obscur "dark, dull, enigmatic," borrowed from Latin obscūrus "dim, dark, appearing faintly, imperfectly known, concealed from knowledge, incomprehensible," of uncertain origin;

  * Note : Latin obscūrus has traditionally been linked to a presumed Indo-European verbal base *skeu̯- "cover, conceal," and hence to an assortment of Germanic etyma, most formed with hypothesized root extensions of this base (compare {shower:1|shower:1}, {sky:1|sky:1})—hence, J. Pokorny, Indogermanisches etymologisches Wörterbuch, p. 951, American Heritage Dictionary, Oxford Latin Dictionary, and the Oxford English Dictionary, third edition. However, etymological work of the last half-century has thrown doubt on the existence of such an etymon; in particular, the Sanskrit verb skunā́ti, glossed as "covers," has now been judged a late and isolated semantic development of a verb that meant "push, poke" in Vedic. The difficulty with any analysis of obscūrus that posits a meaning "cover" for -scūr- is that it makes little sense semantically compounded with the prefix and preposition obs)- "facing, in front of, toward/against" (compare ob oculōs "before one's eyes," obviam "in the way of"). It is not even certain that the word is correctly parsed as ob-scūrus, rather than obs-cūrus, as has been proposed by E. Hamp ("Some Italic and Celtic correspondences II," Zeitschrift für vergleichende Sprachforschung, 96. Band, 1. Heft [1982/83], pp. 98-99). While acknowledging this problem, M. de Vaan suggests a relationship with the bases of Latin scaevus "left-hand" and obscēnus, obscaenus "ill-omened" (see: {obscene|obscene}), though he admits that supporting cognates in other Indo-European languages are lacking (Etymological Dictionary of Latin and the Other Italic Languages, Brill, 2008).;
