Morphology

activation + energy

The meaning is a direct composition of 'activation' (the process of initiating) and 'energy' (power required), so a learner who knows both constituents can infer 'the energy required to start something.' This term is used both in chemistry and metaphorically with the same logic, and similar constructions exist in many languages, making the sense predictable rather than idiomatic.

Etymology

Activation energy is also used in everyday talk for the small first push or effort needed to begin something. The words activation and energy give the image of a 'starting push', so the phrase means the small effort or barrier you must overcome 'to start' a task.
