✕Common Mistakes
Que penses‑tu devoir t'améliorer ?
“Que” does not introduce a “in what” question; use “En quoi” for asking about the domain.
Penses‑tu devoir t'améliorer en quoi ?
The phrase “En quoi” must stay at the beginning of the sentence; moving it to the end sounds ungrammatical.
En quoi penses‑tu devoir améliorer ?
When the verb is reflexive, the reflexive pronoun (t') is required before the infinitive.

Cultural Tip
The construction “En quoi … ?” is considered slightly more formal than “Qu’est‑ce que … ?”. In professional or academic contexts, French speakers prefer the inversion (penses‑tu) rather than the “est‑ce que” form. Also, using the reflexive verb s’améliorer shows personal responsibility, which is valued in French self‑development discourse.
