质问
zhíwèn · HSK 7
interrogate
❓ 质 (nature/substance) + 问 (ask) = demand the real story = interrogate, grill
质 carries the sense of getting at the true nature or substance of something; pair it with 问 (to ask) and you get pointed questioning that demands a straight answer. That is why 质问 means to grill, challenge, or heckle, not just casually ask.
问 — gate 门 (phonetic) + mouth 口 (semantic)
问 is a phono-semantic compound. The 口 (mouth) on the inside gives the meaning—using the mouth to ask—while 门 (gate/door) supplies the sound, close to 'mén/wèn'. The traditional form 問 places 口 inside 門, vividly suggesting speaking through a doorway to inquire.
