Immemorial
adjective /ˌɪm.əˈmɔː.ri.əl/ — Originating in the distant past; beyond the reach of memory.
Definition
Originating in the distant past; so ancient that it is beyond memory or historical record. 'Time immemorial' — the phrase in which the word typically lives — describes origins so old they precede all recollection.
Beyond the definition
Immemorial things carry no history — only presence. They existed before anyone alive can remember, which gives them a different kind of authority. Not documented, not explained, simply: always.
Origin & history
Latin: 'in' (not) + 'memorialis' (of memory). Something beyond the reach of memory — immemorial. In English law, 'time immemorial' originally referred to before the reign of Richard I (1189).
