Morphology

Carnot's + ideal + cycle

The parts 'ideal' (perfect) and 'cycle' (a repeating sequence) transparently yield a general sense of a 'perfect/reversible cycle', so a learner could guess a broad meaning. However, the possessive 'Carnot's' names a specific scientist and signals a technical, domain-specific concept (maximum-efficiency thermodynamic cycle) that cannot be derived from the words alone, so full understanding requires extra background knowledge.

Etymology

Carnot's ideal cycle is named after the French engineer Sadi Carnot, who imagined a perfect engine running in a closed loop. He pictured the machine doing perfect steps that could be reversed, so the words ideal and cycle help you remember it is a simple, perfect model that shows the 'maximum possible efficiency of a heat engine'.
