Questions & Answers about Quiero ponerme este vestido, así que vengo a que estreches la cadera.
Why do we say vengo a que estreches instead of just vengo a estrechar?
When expressing purpose with verbs of motion like venir, you use a + infinitive if the subject is the same (e.g., vengo a estrechar means I come to take it in myself). Because you are coming so that someone else does the action, you must change the structure to a que + the subjunctive (I come so that you take it in).
Why does the verb estrechar end in -es here?
It is conjugated in the present subjunctive. The phrase a que introduces a purpose or future goal, which is seen as unrealized and always triggers the subjunctive. Since estrechar is a regular -ar verb, its tú form in the present subjunctive changes the ending to -es.
The translation says 'to wear', but doesn't ponerse mean 'to put on'?
Exactly. Ponerse literally means to put something on. While an English speaker often says 'I want to wear this dress' when talking about a specific upcoming event, a Spanish speaker will typically express this as wanting to put it on (Quiero ponerme este vestido). To express the continuous state of wearing something, you would instead use llevar puesto.
Why does the sentence use la cadera (the hip) instead of las caderas (the hips) or su cadera (its hip)?
