How it is used
- One's foundation/grounding - accumulated basics or background - 他英语底子好 (tā Yīngyǔ dǐzi hǎo) he has a solid grounding in English.
- Colloquial; also 'the bottom/base' of things or a background/backing color of fabric.
- Contrast 基础 (jīchǔ), the more formal 'foundation'; 底子 is chattier and often about a person's prior grounding.
