Nouns & Declensions
Understanding the five declensions of Latin nouns, their gender, and how case endings indicate grammatical function in a sentence.
Key Fact: Latin nouns change their endings to show their grammatical function in a sentence; this system is called declension.
Key Fact: There are five declensions, each with a characteristic vowel in the stem: 1st (a-stem), 2nd (o-stem), 3rd (consonant/i-stem), 4th (u-stem), 5th (e-stem).
Key Fact: Every Latin noun has a gender: masculine, feminine, or neuter. Gender must be learned with each noun and does not always match natural sex.
Key Fact: First declension nouns are mostly feminine (e.g. puella, villa, familia). Exceptions like nauta and agricola are masculine.
Key Fact: Second declension nouns are mostly masculine (ending -us) or neuter (ending -um). Notable feminine exceptions include humus and vilicus.
Key Fact: Third declension is the largest and most varied group; it contains nouns of all three genders and has both consonant stems and i-stems.
Key Fact: The stem of a noun is found by removing the ending from the genitive singular and adding the neuter -ia: e.g. rex, regis → stem reg-.
Key Fact: Fourth declension nouns are mostly masculine (e.g. adventus, spiritus) with a few neuter (e.g. cornu, genu).
Key Fact: Fifth declension nouns are almost all feminine (e.g. res, dies) and few in number. Dies can be masculine when meaning a set date.
Key Fact: Neuter nouns follow the rule: the nominative and accusative forms are identical in both singular and plural, and the plural nominative/accusative ends in -a.

✅ Answers
- Five: first (a-stem), second (o-stem), third (consonant/i-stem), fourth (u-stem), and fifth (e-stem).
- Mostly feminine. Masculine exceptions include nauta (sailor) and agricola (farmer).
- Remove the genitive singular ending (-is) from the genitive form. For example: rex, regis → stem is reg-.
- The nominative and accusative are always identical in both singular and plural. The plural nominative/accusative ending is -a.
- Fourth declension: adventus (arrival, masculine). Fifth declension: res (thing, feminine) or dies (day, feminine/masculine).
- Gender determines which adjective endings and pronouns agree with the noun. It cannot always be predicted from the declension and must be memorised.
- I-stems have -ium in the genitive plural and -ia in the neuter nominative/accusative plural. Consonant stems have -um in the genitive plural and -a in the neuter plural. I-stems also show -im in the accusative singular for some nouns.
- Masculine: -us (e.g. servus). Neuter: -um (e.g. bellum).
🎯 Exam Tips
- Always learn the nominative AND genitive singular of every noun — the genitive is essential for identifying the declension and stem.
- When translating, identify the noun's case first: the ending tells you its grammatical function in the sentence.
- Watch for neuter nouns: their nominative and accusative look the same, so context determines which case is meant.
- Third declension nouns are the most tested — practise recognising i-stems by their genitive plural (-ium) and neuter plural (-ia).

⚠️ Common Errors
✗ All first declension nouns are feminine. ✓ Most first declension nouns are feminine, but some are masculine (nauta, agricola, poeta, pirata). Gender must be learned individually.
✗ The stem of a noun is found from the nominative singular. ✓ The stem is found from the genitive singular by removing the genitive ending. For example, rex (nom.) has the genitive regis, giving the stem reg-.
✗ Neuter nouns only exist in the second declension. ✓ Neuter nouns appear in the second, third, and fourth declensions (e.g. bellum 2nd, corpus 3rd, cornu 4th).
✗ Fifth declension nouns can be any gender. ✓ Fifth declension nouns are almost all feminine (res, dies, spes, facies). Dies can be masculine only when referring to a specific appointed day.

Full-Mark Response
Explain the Latin declension system, using examples from at least three declensions to show how case endings indicate grammatical function. (6 marks)
The Latin declension system is a set of five groups of nouns that change their endings to show grammatical function (case) and number (singular/plural). Each declension has a characteristic stem vowel. In the first declension (a-stem), puella (girl) has the nominative puella (subject), accusative puellam (object), and genitive puellae (of the girl). In the second declension (o-stem), servus (slave, masculine) shows servus (subject), servum (object), servi (of the slave); while bellum (war, neuter) has bellum as both nominative and accusative. In the third declension, rex (king) has rex (nominative), regem (accusative), and regis (genitive). The case ending signals the noun’s role: the nominative marks the subject, the accusative marks the direct object, and the genitive shows possession. The declension of a noun is identified from its genitive singular ending: -ae (1st), -i (2nd), -is (3rd), -us (4th), -ei (5th). This system allows Latin to use flexible word order because each noun’s grammatical function is clear from its ending rather than its position.
