‘盘问’ is a verb meaning to interrogate or question someone closely, often in a formal, official, or intense setting—such as by police, immigration officers, doctors during diagnosis, or security personnel. The character 盘 (pán) originally means 'to coil' or 'to wind around', suggesting thoroughness and circularity in probing; 问 (wèn) simply means 'to ask'. Together, they evoke the image of repeatedly circling back with questions to uncover truth, verify facts, or detect inconsistencies.

This word carries a slightly stern or serious tone—it implies structured, persistent questioning rather than casual inquiry. It’s commonly used in legal, medical, or administrative contexts, such as during investigations, health screenings, or border control. While not inherently hostile, it suggests authority on the part of the questioner and potential pressure on the respondent. It’s rarely used in friendly or informal conversations—'问' alone or '询问' are more neutral alternatives for everyday questioning.
