Where does “calc” come from?

I need to parse this chain carefully. It appears to have duplicates and some confusion in the ordering (newest to oldest should go backwards). Let me identify the actual chain from oldest to newest: - Proto-Italic -os (suffix) - Ancient Greek χάλιξ (chālix, meaning pebble/gravel) - Latin calx (from Greek χάλιξ, meaning heel or limestone) - Latin calculus (diminutive of calx, meaning small stone/pebble) - English calculation However, the headword is "calc" not "calculation." The chain provided seems corrupted with repetitions. Working with what's supported: The chain goes: Proto-Italic → Ancient Greek χάλιξ → Latin calx → Latin calculus → English For "calc" as a headword with unknown modern meaning, but tracing back through the chain:
