‘讨债’ literally means ‘to ask for (讨) a debt (债)’. It is a verb phrase describing the act of demanding repayment from someone who owes money. The character 讨 carries meanings like ‘to seek’, ‘to demand’, or ‘to request’, often with an assertive or even confrontational tone; 债 specifically refers to money owed — a debt. Together, they form a compact, idiomatic expression used in both formal and informal contexts when someone actively pursues overdue payment.

This phrase commonly appears in daily life — for example, when a small business owner follows up with a late-paying customer, or when family members settle unpaid loans among themselves. While neutral in grammar, ‘讨债’ can imply tension or urgency depending on context and tone. It’s not used for gentle reminders — for those, phrases like ‘请还钱’ (please repay) are softer. Note that ‘讨债’ is never used as a noun (e.g., you wouldn’t say ‘a 讨债’); it functions strictly as a verb.
