How to Say "killing" in Spanish
The most common Spanish word for “killing” is “matando” — use this gerund to describe the ongoing action of 'killing time' or wasting time, not the act of taking a life..
matando
mah-TAHN-doh/maˈtando/

Examples
La policía lo encontró matando el tiempo en el parque.
The police found him killing time in the park.
El cazador estuvo matando mosquitos toda la noche.
The hunter was killing mosquitoes all night.
Forming the 'Doing' Form
Since 'matar' ends in -ar, the gerund (the form that acts like the '-ing' in English) is made by changing -ar to -ando. This is the simplest pattern.
Using Continuous Actions
You combine 'matando' with a form of 'estar' (to be) to show something is happening right now: 'Estamos matando el proyecto' (We are killing the project).
Mixing up Gerund and Infinitive
Mistake: “Using 'estoy a matar' instead of 'estoy matando'.”
Correction: Remember that 'estar' needs the '-ando' form to describe an action in progress. 'A matar' means 'to kill'.
homicidio
/oh-mee-SEE-dee-oh//o.miˈsi.ðjo/

Examples
La policía investiga si fue un accidente o un caso de homicidio.
The police are investigating whether it was an accident or a case of homicide.
Fue declarado culpable de homicidio involuntario.
He was found guilty of involuntary manslaughter.
El índice de homicidios en la capital ha disminuido en los últimos meses.
The homicide rate in the capital has decreased in recent months.
Gender of Nouns
Since 'homicidio' ends in -o, it is a masculine noun. Always use the masculine article 'el' before it: 'el homicidio'.
Confusing Homicidio and Asesinato
Mistake: “Using 'asesinato' when you mean any killing.”
Correction: Use 'homicidio' as the general term for killing a person. 'Asesinato' is specifically used for premeditated or cruel killings, which have a stricter legal definition.
asesinato
/a-se-si-NA-to//asesiˈnato/

Examples
El asesinato del político provocó una crisis nacional.
The assassination of the politician caused a national crisis.
La policía está investigando el brutal asesinato.
The police are investigating the brutal murder.
Fue condenado por intento de asesinato.
He was convicted of attempted murder.
Always Masculine
Like most Spanish nouns that end in '-o', 'asesinato' is masculine. This means you'll always use masculine words like 'el' or 'un' before it: 'el asesinato', 'un asesinato'.
'Asesinato' vs. 'Homicidio'
Mistake: “Using 'asesinato' for any and every killing.”
Correction: In legal terms, 'asesinato' implies premeditation or taking advantage of the victim's defenselessness (it's a planned or particularly cruel murder). 'Homicidio' is the general term for killing another person (homicide), which may or may not be planned.
mortales
/mor-TAH-lehs//moɾˈtales/

Examples
Estas clases de matemáticas son mortales.
These math classes are killing me (extremely boring/hard).
