verlängertem

Verlängertem is the dative masculine/neuter singular form of the German adjective verlängert. This adjective means "extended" or "prolonged" and is derived from the verb verlängern, meaning "to extend" or "to prolong."

In German grammar, the dative case is used to indicate the indirect object of a verb or the object of certain prepositions. When an adjective like verlängert modifies a masculine or neuter noun in the dative singular, it takes the ending "-em."

For example, one might say "mit einem verlängertem Kabel" which translates to "with an extended cable." Here, "Kabel" (cable) is a neuter noun, and "verlängertem" is the appropriate adjectival ending in the dative singular. Similarly, in the phrase "nach einem verlängertem Aufenthalt" (after an extended stay), "Aufenthalt" (stay) is masculine, and "verlängertem" functions as the dative singular form of the adjective. The context of the sentence dictates whether the meaning is "extended" in time or space.
