mystify + somebody

be mystified by + noun

Usage Note

Frequently passive: 'be mystified by/at + noun'. Subject is the puzzling event, behaviour, or object — not a person acting on purpose. Distinguish from sense 2, where someone deliberately makes something hard to understand.

Common Mistakes

The teacher mystified the lesson to the class.
The lesson mystified the class.
the subject of sense 1 is the puzzling thing, not the agent who explains it.
I am mystifying about his answer.
I am mystified by his answer.
the puzzled person is the object or the passive subject, never the present-participle subject.

Sense: verb/1

All five verbs describe a state of not understanding, but they differ in strength and tone. 'Puzzle' is the everyday neutral choice and works for small problems such as a crossword clue. 'Mystify' is stronger and adds the idea that what is happening seems strange or even unexplainable. 'Baffle' goes further still: the puzzle has resisted serious attempts to solve it, which is why doctors and detectives are often 'baffled' in news reports. 'Bewilder' emphasises the feeling of being lost or overwhelmed rather than the search for an answer — a tourist may be bewildered by a noisy market. 'Perplex' is slightly more formal and stresses the intellectual difficulty of a problem. So a child might be puzzled by a riddle, mystified by a magic trick, baffled by an unsolved theft, bewildered by a crowded airport, and perplexed by a difficult exam question.

Etymology

GreekFrenchEnglish

Borrowed into English in the late 1700s from French 'mystifier', which was formed from Greek 'mystēs' (a person who has been initiated into a secret religious rite). The original idea was of holding back knowledge that only insiders could share; over time the meaning shifted to the everyday sense of making someone puzzled or confused.
