ungültigen

Ungültigen is a German adjective derived from the word "ungültig," meaning invalid or void. It is the declined form of "ungültig," used when the adjective modifies a noun in a specific grammatical case, gender, and number. For example, in the sentence "Ich habe einen ungültigen Ausweis gesehen" (I saw an invalid ID card), "ungültigen" is used because "Ausweis" (ID card) is a masculine noun in the accusative case.

The concept of invalidity, or being "ungültig," can apply to various contexts. In legal terms, a contract or a document can be declared ungültig if it does not meet the required legal standards or conditions. This could be due to a lack of proper signatures, being contrary to law, or other procedural defects. In technical or data contexts, an input or value might be considered ungültig if it does not conform to expected formats or ranges, preventing a system from processing it correctly. Similarly, a ticket, coupon, or voucher might become ungültig after its expiration date or if it has been used previously. The specific implications of something being ungültig depend heavily on the domain in which the term is used.
