kündigst

Kündigst is the second-person singular present tense form of the German verb kündigen. It is used when addressing someone informally with the pronoun du. The infinitive kündigen means to terminate, resign from a contract, or cancel something. The present tense forms are: ich kündige, du kündigst, er kündigt, wir kündigen, ihr kündigt, sie kündigen. Therefore, kündigst occurs specifically in sentences addressing the listener.

Usage details:

Kündigst is employed when stating that the person you are speaking to is terminating an agreement or ending a position. Examples include "Du kündigst den Vertrag heute" (You are terminating the contract today) and "Du kündigst deine Stelle zum Monatsende" (You resign from your position at the end of the month). In formal contexts, one would use Sie kündigen instead of du kündigst.

Grammatical notes:

Kündigen is a regular verb. The corresponding past participle is gekündigt, used with haben to form the perfect: "Ich habe den Vertrag gekündigt." The noun form is Kündigung, meaning termination or notice of termination. Related expressions include Kündigungsfrist (notice period) and außerordentliche Kündigung (extraordinary termination).

In summary, kündigst is the du-form present of kündigen, used to indicate that the listener is terminating an agreement or leaving a position in informal German.
