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 phrase warm up comes from the picture of a cold or shy person becoming more open: little smiles and chats make them feel warm inside. That's why it means 'to become more friendly or willing to talk'.
