Where does “monolayer” come from?

I need to work through this chain carefully, but I notice there's a significant problem: the chain provided doesn't actually connect to "monolayer" in a coherent way. The chain shows: - English layer | English lay | Ancient Greek χρῶμα | Proto-Indo-European gʰreu | Latin -are | Latin -are | Latin -arius | Proto-Indo-European ḱel- However, "monolayer" is composed of: - "mono-" (one) + "layer" (a thickness/level) The chain seems to be mixing unrelated etymological paths and contains repetitions (Latin -are appears twice) and doesn't explain how we get from these roots to "layer." For "layer" itself, the actual etymology would trace to Middle English "leier/leyere" from Old English "leger" or from Old French "laiier," relating to
