Morphology

bad + apple

The phrase combines the transparent adjective 'bad' with 'apple' metaphorically: learners will likely infer a negative quality, but the shift from a fruit to a person who negatively influences a group is a cultural/metaphorical mapping not directly derivable from the words alone. The expression relies on the familiar proverb about a rotten apple spoiling the bunch (found in many languages), so it's partly accessible but still requires prior exposure to reach the full idiomatic sense.

Etymology

Bad apple comes from the picture of one rotten apple in a barrel: one bad fruit can make the others go bad. So today a bad apple means a person whose 'bad' behavior can 'spoil' or harm the whole group.
