How to Say "you slew" in Spanish
The Spanish word for “you slew” is “mataste” — A2 level. This is a very common word in everyday Spanish.

You quenched your thirst with that glass of cold water.

Action Completed in the Past
This form uses the simple past tense (Preterite), meaning the action started and finished at a definite point in the past. It is not an ongoing or habitual action.
Specific to 'Tú'
The '-aste' ending is the unmistakable signal that the subject of the verb is 'tú' (the informal 'you'). You use this when talking directly to a friend or someone younger.
Confusing Preterite and Imperfect
Mistake: “Using 'matabas' when referring to a single, specific event.”
Correction: 'Matabas' means 'you used to kill' or 'you were killing.' Use 'mataste' for a single event: '¿Quién mataste?' (Who did you kill?)
Adding an 's' to 'Yo' form
Mistake: “Saying 'yo matastes' (Incorrectly adding the 's' from 'tú' to the 'yo' form).”
Correction: The 'tú' form keeps the 's' ('mataste'), but the 'yo' form does not: 'yo maté' (I killed).
