Using 'Haber' for Existence
When talking about having chemistry, Spanish usually uses a form of 'haber' (hay, hubo) to say that the connection 'exists' between people: 'Hay química entre nosotros' (There is chemistry between us).
❌ Common Pitfalls
Direct Translation Error
Mistake: "Decir 'Tenemos química' (We have chemistry, using 'tener')."
Correction: Aunque se entiende, es más natural decir 'Hay química entre nosotros' (There is chemistry between us), focusing on the shared existence of the connection rather than the possession of it.
