How it's used

Originally describing the jagged, interlocking edges of teeth, this idiom is now primarily used in formal or professional contexts to describe complex, overlapping, or inseparable situations. It carries a sense of structural complexity where elements are so deeply embedded in one another that disentangling them is nearly impossible. While it can be used in spoken Cantonese, it remains a sophisticated literary expression that is rarely used in casual, everyday small talk.

Examples

The businesses of these two companies are so intertwined that it is hard to separate them.

Common phrases

interests are deeply intertwined
relationships are complex and overlapping

Common mistake

Learners often mistake this for a literal description of physical objects like gears or teeth, but it is almost exclusively used metaphorically for abstract concepts like interests, power dynamics, or business operations. Using it to describe simple physical objects will sound unnatural and overly dramatic.
