Morphology

temperature + reduction

The meaning 'a drop in temperature' is directly and compositionally derived from 'temperature' (level of heat) + 'reduction' (process of decreasing), so a learner who knows both words can infer the MWE. This noun + noun composition is a regular, cross-linguistically common pattern and follows standard English compounding, making it immediately comprehensible to B1 learners.

Etymology

Temperature reduction comes from the simple image of making heat go down: temperature is how hot something is and reduction means making it lower. Imagine turning a dial or putting food in a fridge to make it colder. So today it means the process or the moment of a 'drop in temperature'.
