What is the noun for "trigger" when it means something that triggers a reaction?

Question

What is the noun for "trigger" when it means something that triggers a reaction or behavior? For example, if I want to explain that being stressed is a trigger for overeating, how do I say that? Gracias.

I've also been told that "causante" works for "trigger" in this context. Is this a regional term, or understood universally, for "trigger?" - ariyah, Aug 1, 2011

Answer 1

desencadenante, this suits best here.

Answer 2

I use this phrase everyday in my work. This is because i´m a biochemist, and we said "The reaction is trigger triggered by something and vice versa".

The translation used by my colleagues and me is:

La reacción es gatillada por algo.

Sure, this translation is applicable in the scientific colloquial context. Please don´t use it in written translation.

Answer 3

Jajjajaja, seguramente no se usa en España, pero en Chile es común.

Una vez escuché un Español dar una charla y se burló del término usado por nosotros.

Pero tienes razón, es muy coloquial, ni siquiera está aceptado por la RAE.

Answer 4

La reacción es gatillada por algo.

¡Jesús!

Ahora me dirás que gatillar es un verbo?

Aviso La palabra gatillar no está en el Diccionario.

Good good, your Spanish is improving. lol - SpanishPal, Jul 28, 2011

Es cuestión de tiempo que acepten el verbo. Me estoy adelantando a los hechos. :P - Krassa, Jul 28, 2011
