Where does “monocular” come from?

I appreciate the detailed instructions, but I need to flag a critical issue: the etymology chain provided doesn't form a coherent path to "monocular." The chain lists: - English ocular - Ancient Greek μόνος (monos, "single") - Ancient Greek χρῶμα (chroma, "color") - Latin -alis (adjectival suffix) - Proto-Indo-European gʰer- and h₃ekʷ- The problem: "monocular" should derive from Ancient Greek μόνος (monos, "single") + Latin oculus (eye) + -aris/-alis (adjectival suffix). The chain you've provided includes "χρῶμα" (color), which is irrelevant to "monocular," and appears to skip the Latin "oculus" entirely. Before I write the summary sentence,
