4.2 Third declension adjectives

Third declension adjectives expand Latin's descriptive possibilities. They come in three types: two-termination, three-termination, and one-termination, each with unique forms for different genders and cases.

Understanding these adjectives enhances comprehension and translation skills. Mastering their stem formation, case endings, and agreement rules is crucial for accurate Latin composition and interpretation of texts.

Gender agreement

• Three-termination adjectives clearly show gender distinctions (acer, acris, acre)
• Two-termination adjectives use -is for both masculine and feminine (omnis)
• One-termination adjectives employ the same form for all genders (felix)

Number agreement

• Plural forms often differ from singular, especially in nominative and accusative
• I-stem adjectives use -ia in nominative and accusative plural neuter
• Consonant-stem adjectives employ -a in nominative and accusative plural neuter

Case agreement

• Adjectives take the same case as the nouns they modify
• Case agreement applies regardless of word order in the sentence
• Ablative singular often distinguishes i-stem (-i) from consonant-stem (-e) adjectives
• Genitive plural consistently ends in -ium for i-stem adjectives

Comparison to other declensions

• Comparing third declension adjectives to other declensions highlights their unique features
• Understanding these differences aids in proper identification and usage
• Recognizing similarities and distinctions improves overall Latin grammatical knowledge

First and second declension vs third

• First/second declension adjectives have distinct endings for all three genders
• Third declension adjectives often use same form for masculine and feminine
