Tristem

Tristem is the accusative singular form of the Latin adjective tristis, meaning "sad" or "mournful." It is used to modify a masculine or feminine noun in the accusative case.

In Latin, tristis is a two-termination adjective whose endings reflect gender and case. The masculine and feminine nominative singular form is tristis, the neuter nominative and accusative singular is triste, and the masculine and feminine accusative singular is tristem. This form is encountered when the described noun is the direct object of a sentence.

Example: Puellam tristem video, meaning "I see the sad girl." In this sentence, tristem agrees with puellam in gender (feminine) and case (accusative).

Usage notes: Latin adjectives generally agree with the nouns they modify in gender, number, and case, and they can appear before or after the noun. The form tristem is primarily used in classical Latin texts and in linguistic explanations that examine the morphology of tristis. Outside of Latin-language contexts, tristem is not used as a standalone term.
