Morphology

stumbler = stumble (semi-transparent) = stumble + er

The agentive formation 'stumble' + '-er' is clear, but the sense 'person who frequently makes mistakes' is a figurative extension that may not be obvious to all learners.

Etymology

The word stumbler comes from the verb stumble, which means 'to trip or almost fall', and the ending -er means 'someone who'. So a stumbler is someone who 'trips' over tasks or ideas, which is why it can mean a person who often makes mistakes.
