我还没结婚。

You place this phrase after a subject. Usually, that subject is 我 (wǒ), meaning "I." You can use it to answer direct questions about your life. It is a complete sentence on its own. If a nosy relative asks about your ring finger, this is your shield. It sounds natural and grammatically perfect for beginners.

Use it during official paperwork or job interviews. It works great when meeting new friends or colleagues. If you are on a date and the topic comes up, use this. It is also common during those awkward family dinners. In China, elders love to ask about your relationship status. This phrase is your standard, polite response. It keeps the conversation moving without being defensive.

Don't use this if you are already married but just having a bad day. That would be lying! Also, avoid it if you want to sound "cool" or "edgy" about being single. There are slang terms for being a "single dog" for that. If you are divorced, this phrase might be technically tricky. It implies you haven't done it *at all* yet. In that case, just say you are single.

In China, marriage is often seen as a family milestone. People might ask "Are you married?" as a way of showing care. It isn't always seen as prying like it is in the West. By saying 还没 (not yet), you are following a traditional social script. It suggests you are open to the natural progression of life. It’s a very "safe" answer that avoids further interrogation.

You can shorten it to just 还没呢 (hái méi ne) for a casual vibe. If you want to be firm, you can say 我是单身 (wǒ shì dān shēn), meaning "I am single." If you are engaged, you might say 我订婚了 (wǒ dìng hūn le). But for most situations, the original phrase is your best friend. It is clear, polite, and impossible to misunderstand.
