The structure behind the phrase

Why does I want you to come use the subjunctive quiero que vengas?

The answer isn’t the translation — it’s the middle layer, where English word order is rearranged into Spanish logic before a single word is swapped.

The thought · English
I want you to come.
The structure · English in Spanish logic
I-want that you-come(subjunctive).
The Spanish
Quiero que vengas.

The rule

When one subject wants/hopes/asks that ANOTHER subject do something, Spanish links the two clauses with “que” and shifts the second verb into the subjunctive — the mood for things wished-for, not yet real. English uses an infinitive (“to come”); Spanish uses “que + vengas.” The subjunctive flags that the coming is desired, not a fact.

Reading the structure is step one. Feeling it is the moat — watch the words physically rearrange, then say your own sentence and the bartender answers.
