Here is a context clues worksheet on the adjective obscure. This is another of those polysemous words whose array of meanings may surprise you.
In everyday discourse, we mostly use it to mean “not readily understood or clearly expressed.” But it can also mean “dark, dim, shrouded in or hidden by darkness, not clearly seen or easily distinguished, faint”; “relatively unknown, remote, secluded, not prominent or famous”; and, interestingly, “constituting the unstressed vowel \ə\ or having unstressed \ə\ as its value.” Obscure can also be used as a verb, but that’s another worksheet and another post.
