Morphology

hot + on

The sense 'very enthusiastic about' is partially derivable because 'hot' can be used figuratively for strong interest or popularity and 'on' marks the target of that interest, so a learner who knows those figurative uses could infer the meaning. However the adjective+preposition pairing is somewhat idiomatic and relies on a non-literal use of 'hot', so it is not fully predictable for an average B1 learner without prior exposure.

Etymology

Hot on comes from the image of being hot, meaning full of energy, and being on something, like a dog on a trail that is eager to follow. So if someone is hot on an idea or a lead, they are 'very enthusiastic' and focused on going after it.
