Morphology

warm + up

The friendship sense is a metaphorical extension of the literal meanings 'warm' (to become warmer) and 'up' (increase): emotional 'warmth' maps to friendliness and 'warm up' therefore means 'become more friendly'. Because this requires recognizing a metaphorical shift (and phrasal-verb variability across contexts), a B1 learner who only knows the literal senses may not reliably infer the social meaning without prior exposure.

Etymology

Warm up — The verb warm up comes from the simple picture of adding heat, like holding your hands near a fire until they feel warm. That's why it means 'to become warm or to make something warmer'.
