Other forms: rationalised, rationalising, rationalises

To rationalise is to invent a comfortable reason for what you did. Rationalise the decision, easy to rationalise, rationalise it away.

The reason comes after the act, which is the whole point — people decide and then explain, and the explanation feels like the cause. In business the word means something quite different: to cut and simplify. This is the British spelling; American writing has a z.
