Morphology
up + to
The meaning 'having the necessary qualities or ability' is not a direct compositional result of combining the literal senses of 'up' (movement/position) and the preposition 'to'; the phrase functions as a fixed predicative construction whose sense is partly metaphorical. There is a loose connection to 'up' implying readiness or adequacy (cf. 'up for'), but a B1 learner who only knows the individual words would likely need exposure to this idiomatic use, so it is intermediate in transparency.
Etymology
Up to (when we say someone is up to something) one popular story says it comes from the image of a person going up to a hidden place to work on a secret plan. So if someone is 'up to' something, they are busy with it, often in a way that seems suspicious.
