Morphology
The meaning is directly derivable from 'whim' (a spontaneous, often irrational desire) combined with the prepositional pattern 'on + noun' indicating action motivated by that state. This compositional construction is common in English and in many other languages, so a B1 learner who knows the constituent words would readily infer 'on a whim' = impulsively/without planning.
Etymology
On a whim may come from an old short word whim, meaning a small, sudden idea or fancy. Because it names that quick thought that makes you act, on a whim means doing something 'suddenly' or 'without planning'.
