Most first-declension nouns are feminine. Their dictionary entry typically looks like puella, puellae f. “girl”: the nominative ends in -a, the genitive in -ae, and the gender label is feminine. Once that entry is known, the paradigm is highly regular—but several identical-looking endings make syntax and agreement indispensable.
English normally marks a noun’s role by word order and prepositions. Latin can use puella, puellae, puellam, or puellā to show whether the girl is subject, possessor, recipient, object, or an ablative complement. The task is not to replace each ending with one English word; it is to recover case, then interpret the case in its construction. Unless labelled otherwise, the examples below use neutral Classical prose.
Reading the dictionary entry and finding the stem
In puella, puellae f., the genitive puellae identifies the first declension. For practical parsing, remove genitive -ae to find the working base puell-; traditional historical grammar calls this the ā-stem declension because ā belongs to the inherited stem formation and appears clearly in forms such as ablative puellā and accusative plural puellās.
Both descriptions are useful. Puell- is the base to which a beginner can attach the classroom endings; “ā-stem” explains why the declension behaves as a family. Do not assume that every nominative in -a is feminine: agricola, agricolae m. “farmer” has the same endings but masculine gender, and Greek loans may preserve other forms.
The complete paradigm of puella
| Case | Singular | Plural | Core diagnostic |
|---|---|---|---|
| Nominative | puella | puellae | subject or predicate noun |
| Vocative | puella | puellae | direct address |
| Accusative | puellam | puellās | direct object; some prepositions |
| Genitive | puellae | puellārum | possession or another genitive relation |
| Dative | puellae | puellīs | recipient, beneficiary, or governed dative |
| Ablative | puellā | puellīs | means, manner, separation, location, or governed ablative |
Vowel quantity distinguishes accusative singular puellam from accusative plural puellās, and nominative singular puella from ablative singular puellā. Ancient manuscripts do not normally print modern macrons, so a reader must know the quantities even when an edition leaves them unmarked.
Fēmina fīliae fābulam narrat.
The woman tells her daughter a story.
Here fēmina is nominative subject; fīliae is dative recipient; fābulam is accusative object. English uses position and “to,” while Latin uses endings.
Māter puellam ad portam vocat.
The mother is calling the girl to the gate.
Cum puellā per viam ambulō.
I am walking along the road with the girl.
The macron in ablative puellā marks vowel quantity. Viam is accusative after per; being in the same declension does not give the two nouns the same case.
One visible form, four possible analyses
The form puellae can be genitive singular, dative singular, nominative plural, or vocative plural. No pronunciation trick separates these four analyses: the surrounding syntax does.
| Analysis | Example phrase | Clue |
|---|---|---|
| Genitive singular | liber puellae | “the girl’s book”; dependency on another noun |
| Dative singular | puellae aquam dō | recipient of “give” |
| Nominative plural | puellae aquam portant | plural verb portant |
| Vocative plural | puellae, venīte! | direct address and plural imperative |
Liber puellae in mēnsā iacet.
The girl's book is lying on the table.
Puellae aquam dō, quia sitit.
I give the girl water because she is thirsty.
Puellae aquam ex fonte portant.
The girls are carrying water from the spring.
Puellae, ad mē venīte!
Girls, come over to me!
The plural form puellīs is likewise dative or ablative. A verb such as dō may support a dative recipient; cum, ā/ab, ē/ex, dē, or an ablative use may support the ablative.
Magistra puellīs novam fābulam narrat.
The teacher tells the girls a new story.
Magistra cum puellīs ad forum ambulat.
The teacher walks to the forum with the girls.
Gender and agreement
First-declension feminine nouns take feminine agreement even when an adjective belongs to a different declensional class. In via angusta, both words use first-declension endings; in via brevis, the third-declension adjective brevis is still feminine because it agrees with via.
Via angusta ad parvam vīllam dūcit.
The narrow road leads to a small country house.
Via brevis sed difficilis est.
The route is short but difficult.
Adjective position can vary, so agreement—not adjacency—connects the words. See Adjective Agreement for mixed paradigms and separated noun phrases.
Special and marked forms
The regular dative and ablative plural is -īs. The nouns dea “goddess” and fīlia “daughter” can use deābus and fīliābus, especially where a writer wishes to distinguish them from masculine deīs “gods” and fīliīs “sons.” These are Classical lexical exceptions, not a productive ending for all feminine nouns.
Māter fīliīs fīliābusque dōna dedit.
The mother gave gifts to her sons and daughters.
The enclitic -que joins the two dative plurals. The distinctive -ābus makes the contrast immediately visible.
The old genitive singular in -ās survives in expressions such as pater familiās “head of a household.” It is (archaic) and formulaic in Classical Latin; ordinary productive prose uses familiae. Genitive -āī is (archaic) or (literary) and belongs chiefly to early or poetic language. First-declension Greek forms have their own distribution and are treated on First-Declension Greek Forms.
Names of towns can also preserve a locative identical in appearance to the genitive singular: Rōmae “at Rome.” That is a locative function, not a fifth meaning of the genitive, and it belongs to the system explained under Locative Forms of Towns and Small Islands.
Parsing and production workflow
For reading, find the ending, list all matching case-number values, inspect agreement and governing words, then recover the syntactic relation. For writing, choose the noun’s role first and only then select the ending. If you want “with the girl,” cum requires ablative puellā; if you want “toward the girl,” ad requires accusative puellam.
The nominative alone never supplies the whole lexical entry. Puella strongly suggests the first declension, but only puellae confirms it, and only f. licenses feminine agreement. This habit becomes essential when less transparent declensions appear.
Common Mistakes
1. Using the nominative for a direct object
❌ Māter puella vocat.
Incorrect for ‘the mother calls the girl’: puella is nominative.
✅ Māter puellam vocat.
The mother calls the girl.
2. Treating every puellae as plural
⚠️ Puellae aquam dō.
As written, this means ‘I give the girl water’; a plural recipient would be puellīs.
✅ Puellae aquam dō.
I give the girl water; the dative singular puellae marks one recipient.
3. Ignoring vowel quantity in the ablative singular
❌ Cum puella ambulō.
Incorrectly marked teaching form: after cum, the form is ablative puellā with long ā.
✅ Cum puellā ambulō.
I am walking with the girl.
4. Guessing gender from -a alone
❌ Agricola bona ad forum venit.
Incorrect for a male farmer: agricola is first-declension but grammatically masculine.
✅ Agricola bonus ad forum venit.
The good farmer comes to the forum.
Key Takeaways
The regular first-declension feminine paradigm is predictable once nominative, genitive, and gender are known. Its main challenge is syncretism: -ae and -īs each represent several functions. Use syntax, agreement, and governing words to choose among them, and preserve the long vowels of -ā, -ās, -ārum, and -īs in teaching forms.
