adhuc

Adhuc is ad plus huc, "to this point", and the shape tells you the meaning: it measures from the past up to the present moment and stops there. "So far, up to now, still."

Classical prose keeps it to that. For "still" in a past narrative, where the reference point is not now but some moment in the story, careful writers use etiam tum or etiam nunc instead. Later Latin relaxes the rule and lets adhuc float freely, so a text that uses it of the past is telling you something about its date. With a negative it is "not yet": adhuc nihil audivi.

Keep it apart from the two adverbs it sits nearest. Iam marks a CHANGE of state, "now, already, by this time", and often implies that things were otherwise before. Etiam ADDS, "also, even, still more". Adhuc simply extends what has been true up to the present. Res adhuc integra est, "the matter is still untouched", is the standard Roman way of saying nothing has been decided yet.
