Mnemonic
The short human-readable name for a CPU instruction, such as MOV, PUSH, or CALL, used in assembly language.
A mnemonic is the symbolic shorthand a programmer or disassembler uses to represent a CPU instruction — for example MOV, PUSH, CALL, or JNZ. Each mnemonic corresponds to one or more opcodes depending on the operands involved. Mnemonics are defined by the CPU's instruction set architecture and are assembled into raw bytes by an assembler. Reading mnemonics fluently is the baseline skill for any reverse engineer working at the assembly level.
