Sentence-finishers (Someone who interrupts - Interruptor)

[Glen]

We all know the kind of person who stops us in mid-sentence to complete - in his own words - what he imagined we were about to say. An "interruptor," in English. But that's a false cognate, so what would such a person be called in Spanish? Is there a noun form of the verb interrumpir?

[Rusty]

The noun form happens to be a noun clause.

el que interrumpe (la conversación)
el que corta la palabra

Other phrases:
cortar la palabra
entrometerse en la conversación
atravesarse con la palabra mientras otro está hablando

By the way, I found two people on the internet who used 'interruptor' as a noun meaning 'one who interrupts' instead of 'something that interrupts'.
Look up 'enemigos de la conversación'.


~~~
A 'false cognate' 'false friend'.

I don't mean to split hairs, but 'interruptor' is a cognate of the English 'interruptor', when this word refers to a switch.
It is a 'false friend' when the meaning is the person who interrupts a conversation.

[JPablo]

Probably, "una persona cortante" or "persona muy cortante"

In a Spanish (Spain) slang "un tío que corta el rollo",

In other ways (just a guess...?)

"Un güey que te corta/que no te deja hablar"...

Well, DRAE also gives,
interruptor, ra.
(Del lat. interruptor, -ōris).
1. adj. Que interrumpe.
2. m. Mecanismo destinado a interrumpir o establecer un circuito eléctrico.

Vaya, sin el contexto del hilo interpretaría eso como un aguafiestas.

An alternative name is 'wife'
