The word 'they' originates from Old Norse 'þeir', the masculine plural demonstrative pronoun, which was adopted into Old English during the Viking Age. It replaced the native Old English plural pronoun 'hīe', providing a clearer distinction from the singular forms 'hē' (he) and 'hēo' (she). This borrowing was part of a significant Norse influence on English pronouns, also giving us 'them' and 'their'. Over time, 'they' evolved from its specific plural and demonstrative origins in Norse to become the standard third-person plural pronoun in Modern English, and more recently, has gained widespread acceptance as a singular pronoun for a person whose gender is non-binary or unspecified.
