The word じろじろ is part of a cluster of related adverbs.

  • じろじろ -- First cited to 1700. Found in some older texts as ぢろぢろ.
  • じろり -- First cited to 1871. Found in some older texts as ぢろり.
  • じらり -- Date unknown. No actual dictionary entry for this, although it is listed as a synonym in the じろり entry.
  • じろっと -- First cited to 1903. Found in some older texts as ぢろっと.

All of these have to do with "moving the eyes and staring pointedly".

I had first thought that maybe the じろ was a shift from しろ and had to do with the whites of the eyes somehow, and the voicing indicated a softer or rounder kind of motion. However, the root is clearly ぢろ, not じろ. I'm not sure how this sound symbolism plays out; the initial ぢ is certainly unusual. It's possible that the initial ぢ arose as a kind of emphasis of じ, in which case this might still be related to the whites of the eyes, and / or to adverb じっと ("fixedly").

The ろ seems to be related to, or at least suggestive of, the ろ in adverbs like ぎょろぎょろ ("rollingly", as when rolling one's eyes) or ころころ ("rollingly", as when something rolls around).
