What does checker mean?
A checker is fundamentally someone or something that checks — that is, examines, verifies, or inspects for accuracy and completeness. The word appears most often today in compound roles such as fact-checker, spell-checker, and baggage checker, reflecting modern reliance on systematic verification. In American usage, a checker is also the employee who rings up purchases at a supermarket checkout, a role known elsewhere as a cashier or checkout assistant. A third, distinctly American sense names one of the round pieces moved across the board in the game of checkers, the US name for what Britons call draughts. All of these meanings trace back through the same root: the Persian word shah, meaning king, which entered English via Arabic and Old French through chess terminology. The verb form, to check, remains among the most common verbs in English, making checker a natural agent noun from a deeply embedded word family.
A person or device that examines or verifies something for accuracy, quality, or correctness.
"The airport's baggage checker identified several oversized items during screening."
Most common in compounds such as fact-checker and spell-checker.
(US) An employee who totals and collects payment for goods at a retail checkout.
"The checker scanned each item quickly while chatting with the customer."
Chiefly North American; British English prefers 'checkout assistant' or 'cashier'.
One of the flat, usually round pieces used in the game of checkers (draughts).
"He moved his checker into position for a double jump."
Note that 'checkers' is also the standalone name of the board game itself in American English, so the plural can refer either to multiple individual agents/pieces or to the game as a whole depending on context.
"The store scheduled extra checkers for the weekend sale."
The same word that names the person scanning your groceries also names the little disc you jump over on a checkers board — two senses born from one ancient Persian word: shah, meaning king.

Etymology of checker
Checker derives from the verb 'check', which entered Middle English around the fourteenth century from Old French 'echec' ('a check at chess'), ultimately tracing back through Arabic 'shāh' to the Persian 'shāh', meaning king — the same origin behind 'checkmate' (from 'shāh māt', 'the king is dead'). The agent-noun suffix '-er' produced 'checker', literally 'one who checks'. The spelling variant 'chequer' reflects French-influenced orthography retained in British English, while American English standardized on 'checker'. Cognates and relatives include 'cheque' (the banking term), 'chess', and 'checkmate', all descending from the same Persian royal lineage.

How checker is actually used
In British English, 'checker' as a supermarket cashier is rare — 'checkout assistant' is preferred. The gaming sense (a draughts piece) is primarily American, since the board game itself is called 'checkers' in the US and 'draughts' in the UK. The spelling 'checker' dominates American English, while British English traditionally uses 'chequer' in related forms like 'chequered'.
