  • makes decisions impulsively

Origin

The expression is an old paired formula based on the juxtaposition of two words with negative or extreme meanings.

Tonto originally refers to someone foolish or lacking judgement, while loco refers to someone considered irrational or lacking reason.

The combination came to describe behaviour carried out without reason, order or deliberation.

The feminine forms tontas and locas are fossilised in the traditional expression and do not normally refer to actual women.

Cultural note

The expression often carries a mild criticism of the person's lack of organisation or judgement.

For example:

Está gastando el dinero a tontas y a locas.

This does not simply mean:

He's spending money randomly.

It suggests:

He's spending money recklessly and without thinking.

The expression can therefore imply carelessness or irresponsibility, not merely randomness.

Did you know?

A tontas y a locas belongs to a very productive Spanish tradition of paired expressions:

  • Sin ton ni son
  • Sin orden ni concierto
  • A tontas y a locas
  • A troche y moche
  • A diestro y siniestro

These formulas often combine words for their rhythm, contrast or sound, creating a memorable expression whose overall meaning is not simply the sum of its individual words.

For English speakers

Do not translate:

Lo hizo a tontas y a locas.

as:

He did it to silly women and crazy women.

The natural translation is:

He did it haphazardly.

He did it without thinking.

He did it in a completely random way.
