memorable

The word 'memorable' has a transparent construction from its Latin components. It stems from the Latin adjective memorabilis, meaning "worth mentioning or remembering," which itself is formed from memor (mindful) and the suffix -abilis (expressing capacity or worthiness). The root memor can be traced back to the Proto-Indo-European (s)mer- (to remember, care for), a root also giving rise to words like 'memory,' 'mourn,' and 'martyr.' Thus, the literal sense of "capable of being remembered" evolved seamlessly into the modern meaning of something so noteworthy or exceptional that it naturally remains in one's mind.

Structure: memor (memory) + able (capable of) - memor: Latin origin, from memor (mindful, remembering). Functions as the core root denoting memory. - able: Latin origin, via Old French, from Latin -abilis (capable of, worthy of). Functions as an adjective-forming suffix.
