Dependent on someone or something for support, help, or supply.
From Old French relier meaning 'to bind together', from Latin religāre (re- 'again' + ligāre 'to bind'). The English word evolved through 'rely' in the 14th century, with 'reliant' appearing in the 16th century to describe the state of depending on others.
The etymology reveals a beautiful metaphor - to be reliant literally means to be 'bound again' to someone or something. This binding imagery appears across languages when describing dependence, suggesting humans universally conceptualize relationships as forms of connection or attachment.
