other

Other is a word used in English as a determiner, adjective, or pronoun to refer to something different from what has already been mentioned or to indicate an additional person or thing. It can modify a noun, as in other ideas or other people, or stand alone as a pronoun, as in the others. The phrase the other typically signals a single item among a known set, while other denotes the remainder or items of a different kind. This contrasts with another, which usually points to a single additional item.

Etymology and cognates: The word originates in Old English oþer and comes from Proto-Germanic roots. It has cognates in several Germanic languages, such as Dutch ander and German anderer/andere, reflecting a common semantic field related to difference or alternation. Over time, other acquired broader uses beyond its original sense of “the second of two,” expanding into generalized meaning of “additional” or “different.”

Usage in data and classification: In surveys, databases, and taxonomies, Other functions as a catch-all category for responses or items not listed among predefined options. It is often paired with a Please specify field to capture non-listed inputs. While useful for avoiding forced choices, the category can obscure distinct subgroups if not collected and analyzed carefully.

In computing, linguistics, and information organization: Other commonly appears as a broad class label in machine learning, tagging, and metadata schemas. It serves as a non-specific option that may require later normalization or disaggregation to prevent ambiguity and ensure clarity in data interpretation.

Cross-linguistic note: Equivalent terms exist across languages, typically used to indicate non-specified or differing items. Although the exact sense can vary by context, the core idea of “not the ones already mentioned” remains central.
