Word Origin

From the verb 'default' (Middle English, from Old French 'defaulter' meaning 'to fail to fulfill a duty') combined with 'value' (from Latin 'valere' – to be strong, worth). The phrase entered computing jargon in the 1960s with early programming languages that allowed automatic initialisation of variables.

Usage Notes

Common in programming, databases, and configuration files. Always check documentation because a default value may not be the optimal or safest choice.
