Morphology

In computing 'postfix' refers to notation with operators placed after operands, which follows the literal 'after' + 'attach' logic of the components.

Etymology

Postfix comes from the parts post- 'after' and fix 'attach', so in postfix notation the operator is written 'after' the numbers, for example '5 6 *' means 5 times 6.
