Synonym discussion

Sense: adjective/1

Lifelong, permanent, enduring, and lifetime all describe things that last a long time, but they differ in scope and connotation. Lifelong is the most specific — it means exactly 'from birth to death,' so it pairs naturally with friend, dream, passion, or habit. Permanent means 'never changing or ending,' which is broader (a permanent job may or may not last a lifetime). Enduring stresses the ability to survive hardship (an enduring love survives difficult times). Lifetime, grammatically a noun used as an adjective, is very close to lifelong but often appears in more formal or institutional contexts (a lifetime achievement award). You can have a lifelong friendship without it being particularly enduring, and you can have a permanent address that you change after a few years. Choose lifelong when the defining feature is the span of a human life.
