Main Meaning
Definition
Dependent functions as both an adjective and a noun in American English. As an adjective, it means relying on someone or something for support, or determined by something else. As a noun, it refers to a person who relies on another for financial support. Dependant is a noun used only in British English, referring to a person who depends on another for financial support, especially a family member.
Origin
Both words trace to the Latin verb dependere, meaning “to hang from” or “to be connected with,” combining de- (“down”) and pendere (“to hang”). The word entered English in the 15th century. The spelling distinction between “dependent” and “dependant” emerged in the 18th century, primarily in British English, to distinguish the noun from the adjective.
Context
The distinction matters across several contexts:
- American English: “Dependent” is used for both adjective and noun forms
- British English: “Dependent” is the adjective; “dependant” is the noun
- Tax and Legal Documents: Spelling varies by jurisdiction
- Insurance Forms: American forms use “dependent”; British forms use “dependant”
- Academic Writing: Style guides vary by region
Modern Usage
Today, “dependent” dominates in American English across all contexts. In British English, both spellings coexist with distinct roles: “dependent” for the adjective, “dependant” for the noun. Canadian English generally follows American conventions, though both spellings appear. Australian English follows British conventions. The confusion persists because the words sound identical and the distinction is subtle.
