- SOUND
- Calculus has traditionally been treated as an irregular diminutive of calx, but the phonology and meanings are problematic and a shared non-Indo-European source with a Greek stone-word has been proposed.
- MEANING
- A small stone or pebble may connect to lime or limestone; the route is unsettled.

- Calculāre is derived from calculus.
- MEANING
- Manipulating counting pebbles becomes the general act of computation.
STEP 03borrowingestablished
- SOUND
- English borrowed Latin calculus without a mediating vernacular form in the reviewed route; pronunciation and plural behavior were anglicized.
- MEANING
- Latin counting and reckoning specialize into mathematical systems while the bodily-stone sense also survives.

“Every” means every descendant in the reviewed SET-U graph. It does not convert missing scholarship or missing ingestion into a claim of historical completeness. The coverage ledger remains the honest denominator.
