Here is a context clues worksheet on the verb stun. It’s used only transitively, so don’t forget you direct object: the subject of the sentence must stun someone or something.
The verb means, variously, “to make senseless, groggy, or dizzy by or as if by a blow,” “daze,” “to shock with noise,” and “to overcome especially with paralyzing astonishment or disbelief.” In other words, this is a nice solid verb with a wide but coherent range of meanings that students, by the time they graduate high school, I submit, should know and be able to use proficiently.
