memoir

The word 'memoir' entered English in the late 15th century from the French 'mémoire', meaning "memory" or "written record." The French term itself derives from the Latin 'memoria', meaning "memory" or "remembrance," which originates from the root 'memor' (mindful). The core semantic link is the act of remembering. Over time, the meaning shifted from the general faculty of memory to a specific written account based on personal recollection, reflecting a move from the internal mental process to its external, documented product. The suffix '-oir' (from Latin '-orium') standardly denotes a thing connected to an action or function, thus a 'memoir' is literally "a thing pertaining to memory."

Structure: mem (mind, memory) + oir (noun suffix) - mem: From Latin memor (mindful, remembering). Functional role: root conveying the core meaning of memory or recollection. - oir: From Old French -oire, a suffix forming nouns. Functional role: derivational suffix indicating a thing associated with the root concept.
