Questions & Answers about L'insegnante è assente.

Why is there an apostrophe in L’insegnante?

Italian drops the vowel of the definite article il (masc. sg.) or la (fem. sg.) before a noun that starts with a vowel. So il insegnante or la insegnante both become l’insegnante. The elision itself doesn’t show gender—you’d need context or an adjective to know if the teacher is male or female.

Is insegnante masculine or feminine?

insegnante is a common‐gender noun: it looks the same for masculine and feminine. You mark gender with the article or an adjective:
• l’insegnante bravo = the (male) teacher
• l’insegnante brava = the (female) teacher
For an indefinite feminine form you’d say un’insegnante.

Why is assente placed after è, and can I use it directly after the noun?

Here assente is a predicate adjective, so it needs the verb essere (è) to link the subject and adjective—“The teacher is absent.”
If you drop the verb, you can still say l’insegnante assente, but that’s a noun phrase (“the absent teacher”), not a complete sentence expressing state.

How does assente change for gender and number?
