"Our temple is sacred and beautiful."
Translation:Templum nostrum est sacrum et pulchrum.
In neuter nouns, the nominative and the accusative are always identical. For a second-declension neuter noun like templum, both NOM and ACC singular are templum, while NOM and ACC plural are templa. All other forms are the same as the rest of the second-declension forms (GEN sing templī, DAT/ABL sing templō, GEN pl templōrum, DAT/ABL pl templīs).
