- SOUND
- Latin calculus may be a borrowing from the same unidentified source as Greek káchlēx; no donor form is reconstructed.
- MEANING
- Both words denote a small stone or shoreline shingle, but the direction and mechanism of transmission are unknown.
- SCHOLAR
- Merriam-Webster editors summarizing Beekes
- CONFIDENCE
- proposed — This is a shared-source hypothesis, not a Greek-to-Latin ancestry claim.

- SOUND
- Greek káchlēx and its cited variants display alternations Beekes treats as substrate signals; no donor form is reconstructed.
- MEANING
- The Greek shoreline-shingle word may share an unidentified source with Latin calculus.
- SCHOLAR
- Merriam-Webster editors summarizing Beekes
- CONFIDENCE
- proposed — The alternations motivate a substrate hypothesis but do not identify a historical donor language or form.

- SOUND
- Calculāre is derived from calculus.
- MEANING
- Manipulating counting pebbles becomes the general act of computation.
STEP 02borrowingestablished
- 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.

- Calculātus is the past participle of calculāre.

- SOUND
- Latin calculātor is an agent noun in -tor formed from the stem calculā- of calculāre.

- SOUND
- English borrowed the learned participial stem with regular English stress and suffix treatment.
- MEANING
- Counting and reckoning broadened into estimation, intention, and deliberate planning.

- Middle English calkelatour adapts Latin calculātor with vernacular vowel and consonant spelling.
- MEANING
- The Latin arithmetic teacher or reckoner remains a person who counts or computes.

- SOUND
- Middle English calkelatour loses unstressed material and stabilizes with the learned agent ending -or as calculator.
- MEANING
- The human reckoner sense survives while the agent label later transfers to mechanical and electronic calculating devices.
“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.
