Questions & Answers about Emblema pulchrum est.
Because pulchrum has to agree with emblema.
In Latin, adjectives agree with the nouns they describe in gender, number, and case. Here:
- emblema is neuter
- it is singular
- it is nominative (the subject form)
So the adjective must also be neuter nominative singular, which is pulchrum.
That is why Latin uses:
- pulcher for a masculine noun
- pulchra for a feminine noun
- pulchrum for a neuter noun
Because not every Latin noun ending in -a is feminine.
A beginner often learns that nouns ending in -a are usually first declension feminine nouns, but emblema is different. It is a Greek loanword in Latin, and its dictionary form is:
- emblema, emblematis, neuter
So its -a ending here does not mean it is feminine. It is simply the nominative singular form of this particular neuter noun.
This is a very common kind of beginner question, because the ending looks misleading at first.
