Noticed

Noticed is the past tense and past participle of the English verb notice. It means to become aware of something through perception or to observe something that was previously unseen or unrecognized.

Etymology: The verb notice derives from the noun notice, which in turn comes from Old French notice, from Latin notitia, meaning knowledge or awareness. The verb entered English in the late Middle Ages as a direct extension of the noun’s sense of perception.

Grammar and usage: Noticed is transitive; it takes a direct object, as in "She noticed a discrepancy in the report." It can be followed by a that-clause: "I noticed that he was tired." It can appear in passive constructions: "The problem was noticed by several readers." It forms the present perfect with have: "I have noticed an improvement."

Usage notes: Noticed is common in both formal and informal contexts. The related noun is notice; the adjective is noticeable; and the present participle is noticing. The phrase take notice means to pay attention or acknowledge something: "Take notice of the warning."
