glark

glark /glark/ vt.  To figure something out from context.
   "The System III manuals are pretty poor, but you can generally
   glark the meaning from context."  Interestingly, the word was
   originally `glork'; the context was "This gubblick contains many
   nonsklarkish English flutzpahs, but the overall pluggandisp can be
   glorked [sic] from context" (David Moser, quoted by Douglas
   Hofstadter in his "Metamagical Themas" column in the January
   1981 "Scientific American").  It is conjectured that hackish
   usage mutated the verb to `glark' because {glork} was already
   an established jargon term.  Compare {grok}, {zen}.
