observées

Observées is the feminine plural form of the past participle of the French verb observer, and it also functions as an adjective meaning “observed.” It appears in two main roles in French grammar: as part of compound tenses with an auxiliary, and as a descriptive attribute for feminine plural nouns.

As a past participle, observées participates in compound tenses with the auxiliary avoir or être. When the auxiliary is avoir, the participle agrees with a preceding direct object. For example: “Les observations que nous avons observées permettent de tirer des conclusions” (observations is feminine plural, and the participle agrees). When the auxiliary is être, the participle agrees with the subject: “Elles ont été observées” (feminine plural subject).

As an adjective, observées agrees in gender and number with the noun it modifies. For instance: “données observées” means “observed data” (données is feminine plural), and “échantillons observés” would use the masculine plural form for a masculine subject.

Etymology and usage notes: observées derives from observer, via the feminine participle ending -ée, and is common in scientific, academic, and descriptive writing. It frequently appears in contexts involving data collection, experiments, fieldwork, and reports where results, events, or phenomena are described as having been observed.

Common related forms include observé (masculine singular), observée (feminine singular), and observés (masculine plural). The form observées, therefore, marks feminine plural agreement and is essential for correct agreement in both verbal and adjectival uses.
