Is recognise a word?
Recognise is the more common British English spelling of recognize. It is considered incorrect in American English.
Most words that end in “-ize” are more usually spelled “-ise” in British English, although the Oxford University Press and Oxford English Dictionary prefer “-ize.”
Whichever way you spell it, recognise/recognize is a regular verb that means “identify something or someone that is already known” (e.g., “Hai wasn’t sure his teacher would recognise/recognize him after so long”) or “acknowledge someone’s efforts or achievements” (e.g., “The award was given every year to recognise/recognize the most community-minded student”).
