'stoic' originates from Greek, specifically the word 'stōïkos,' where 'stoa' meant 'porch,' referring to the painted porch where Zeno taught.

'stōïkos' transformed into the Latin word 'stoicus,' and eventually became the modern English word 'stoic' through Middle English.

Initially, it referred to a member of the ancient philosophical school of Stoicism, but over time it evolved into its current meaning of enduring pain or hardship without complaint.
