recognises

Recognises is the British English spelling of the verb to recognize. It means to identify someone or something from previous knowledge, to acknowledge or admit, or to distinguish one thing from another. It can also mean to recall from memory or to accept something as valid.

In present tense, third-person singular uses recognises: She recognises her friend in the crowd. The verb forms include recognising (present participle) and recognised (simple past and past participle) in British English. American English uses recognizes, recognizing, and recognized.

Etymology: The word derives from Latin recognoscere, re- + cognoscere, meaning to know again or to recall, and entered English via Old French reconnaître.

Spelling variants and related forms: recogniser (a person or device that recognises) is common in British usage, though many American contexts prefer recognizer. The noun form is recognition. Adjectives include recognizable and recognisable, with the latter form more common in British English and the former in American English.

Usage notes: Recognise is widely used in everyday speech as well as formal writing. It appears in law, education, science, and technology, including terms like facial recognition, pattern recognition, and recognisable signs of truth or illness. When translating or switching between varieties of English, the spelling shift between recognise and recognize should be observed, as well as related forms such as recognisable versus recognizable.
