A friend assumes you don't want to join them, but the real problem is your packed schedule — and you can't find the right words to set them straight. The pattern 不是...而是 (búshì...érshì) — Not A, But Rather B (Correction) — exists for exactly this situation: you deny the wrong assumption first, then replace it with the truth.
The structure is simple: 不是 + A，而是 + B. Place the mistaken idea after 不是 and the real reason after 而是. The key sentence for this lesson is:
我不是不想去，而是没有时间 (wǒ búshì bù xiǎng qù, érshì méiyǒu shíjiān) — "It's not that I don't want to go — it's that I don't have time."
Use this pattern whenever someone has the wrong idea about your intentions or feelings and you want to set the record straight without sounding defensive.
This Correcting Misunderstandings lesson is a live voice conversation with AI teacher Mei Lin — you talk out loud, not type. Over roughly 10 minutes, Mei Lin gives you scenarios where someone misreads your intentions, and you respond using 不是...而是 in real time. She corrects your grammar and pronunciation in the flow of conversation and adapts to your level, so you build the reflex of Correcting Misunderstandings naturally rather than memorizing a formula.
You can try the first lesson free.

不是...而是 (búshì...érshì) means "Not A, But Rather B." You use it to correct a wrong assumption by denying the false idea after 不是 and stating the real reason after 而是. For example, 我不是不想去，而是没有时间 means "It's not that I don't want to go — it's that I don't have time." It's an HSK 4 grammar pattern for Correcting Misunderstandings.
Each live conversation lesson targets one grammar pattern and takes roughly 10 minutes. In this lesson, you practice Not A, But Rather B (Correction) by speaking out loud with AI teacher Mei Lin, who corrects your grammar and pronunciation as you talk through scenarios where someone misreads your intentions.
No — this is a voice conversation. You talk out loud with Mei Lin in real time, and she responds, corrects, and adapts to your level. The goal is building the reflex of using 不是...而是 spontaneously in speech, not typing sentences.
