Purpose with motion verbs (a que)

Coming and Going for a Purpose

When you go somewhere to do something yourself, you use a motion verb like ir (to go) or venir (to come) followed by a and an infinitive. But if you go somewhere so that someone else does something, use a que followed by the present subjunctive.

This signals a change in subject—for example, visiting the tailor so that they can let out (ensanchar) or take in (estrechar) your clothes.

Good morning, I've come for you to let out the waist of these pants.
Buenos días, vengo a que ensanches la cintura de este pantalón.
I want to wear this dress, so I've come for you to take in the hip.
Quiero ponerme este vestido, así que vengo a que estreches la cadera.

Shortening and Lengthening

Whether you need a professional to shorten (acortar) or lengthen (alargar) your clothes, remember the formula: ir / venir + a que + subjunctive.

I've been coming to this shop for years for you to shorten my clothes.
Llevo años viniendo a esta tienda a que acortes mi ropa.
The coat is still very short, so she's going to the workshop for them to lengthen it.
El abrigo todavía es muy corto, por eso va al taller a que lo alarguen.

Major Alterations

Use this same structure for any repair, like asking the dressmaker to unstitch (descoser) an old lining (el forro) or mend (remendar) a hole with a patch (el parche).

I'm going to the dressmaker for her to unstitch the old lining of the jacket.
Voy a la modista a que descosa el forro viejo de la chaqueta.
We've come for you to mend the lining with a patch.
Venimos a que remiendes el forro con un parche.
She's going to the dressmaker for her to unstitch the buttons and let out the chest.
Va a la modista a que descosa los botones y ensanche el pecho.
