Questions & Answers about Feles in cellario manet, ut murem capiat.
Because feles, felis is a third-declension noun whose nominative singular happens to end in -es. In Latin, an ending like -es is often plural, but not always.
Here, feles is singular, and you can confirm that from the verb manet, which is also singular: the cat stays.
Manet is the 3rd person singular present active indicative of maneo, manere.
It means stays, remains, or waits depending on context. In this sentence, it describes what the cat is doing now.
Because in with the ablative usually means in or inside, showing location.
So:
- in cellario = in the cellar / in the pantry
- location, not movement
If the sentence meant into the cellar, Latin would normally use in with the accusative:
- in cellarium = into the cellar
