bygone

The word 'bygone' is a transparent compound formed from two native English elements. The prefix 'by-' carries the sense of "past" or "by," as seen in other temporal words like 'bypast'. The core element 'gone' is the past participle of the verb 'to go,' literally meaning "having passed away." The compound, emerging in the 15th century, logically and vividly constructs the meaning of "past" from the literal idea of "having gone by." Its evolution is a clear example of how Germanic languages create abstract temporal concepts from concrete spatial and action-based roots, with the modern sense retaining this direct metaphorical link to elapsed time.

Structure: by (past) + gone (gone) - by: Old English origin, meaning "near, past, secondary." In this compound, it functions as a prefix indicating something that is past or over. - gone: Old English origin, past participle of the verb 'go'. In this compound, it functions as the core element meaning "having departed or passed."
