Definition:
Wh-movement is a syntactic operation in which a question word (wh-word: who, what, where, when, why, how) moves from its base position in the sentence to the front (specifier of CP in formal syntax). In English, “What did you eat?” moves “what” from the object position (“You ate what”) to the beginning. Not all languages do this — Japanese is a wh-in-situ language where question words stay in their base position.
In-Depth Explanation
Languages with wh-movement (English, French, Spanish, etc.):
- Base: “You ate what.” → Surface: “What did you eat __?”
- Base: “She went where.” → Surface: “Where did she go __?”
- The wh-word moves to the front, and the original position is left empty (a “trace” or “copy”)
Wh-in-situ languages (Japanese, Korean, Mandarin, etc.):
- 何を食べましたか？ (Nani wo tabemashita ka?) — “What [ACC] ate [POL-PAST] [Q]?”
- The question word 何 (nani, “what”) stays right where the answer would go
- Only the question particle か (ka) at the end signals that it’s a question
| English (wh-movement) | Japanese (wh-in-situ) | |
|---|---|---|
| “You ate ramen.” | “You ate ramen.” | ラーメンを食べた。 |
| “What did you eat?” | “What did you eat __?” | 何を食べた？ |
| Question word position | Moved to front | Stays in place |
| Question marking | Word order + auxiliary | Particle か or rising intonation |
Why this matters for learners:
Japanese learners of English must learn to move the question word to the front AND insert an auxiliary verb (do/did/does) — two operations that don’t exist in Japanese:
- Common error: *”You ate what?” (using Japanese-style in-situ question)
- Correct: “What did you eat?”
English learners of Japanese must learn to suppress the movement instinct:
- Common error: *何を食べた？ sounds fine, but learners may be tempted to front-load the question word in more complex structures where it sounds unnatural
Wh-movement also creates long-distance dependencies that are challenging: “What do you think she said __?” — the gap is two clauses away from “what.” Japanese avoids this complexity by keeping the question word where the answer goes.
