Morphology

NAND + circuit

The noun 'circuit' is transparent, but 'NAND' is a technical acronym (NOT-AND) not present in the learner dictionary entry and requires specific knowledge of logic-gate naming. If a learner knows that 'NAND' means the negation of an AND operation, the combined meaning is predictable, but for an average B1 learner without that technical background the compound is not fully derivable.

Etymology

NAND circuit comes from joining NOT and AND to show it is the opposite of an AND. Think of two switches in a row: an AND lets power flow only when both are on, while a NAND is the opposite — it is 'false' only when both inputs are 'true', so the name reminds you it means 'not-and'.
