Questions & Answers about Der Rückgabetermin ist morgen.

Why is it der Rückgabetermin and not die or das?

Because Rückgabetermin is a masculine noun.

A very useful rule for German compounds is: the last part usually decides the gender.
Here, the last part is Termin, and you say:

• der Termin

So the full compound is also masculine:

• der Rückgabetermin

In this sentence, it is also the subject, so the nominative article der is the correct form.

Why is Rückgabetermin written as one long word?

Because German very often combines nouns into a single compound noun.

This word is made from:

• Rückgabe = return
• Termin = date / appointment / scheduled time

So German makes one word:

• Rückgabetermin

English usually writes these ideas as separate words, such as return date or due date, but German prefers one compound noun.
