Etymology

The word "pocket" traces back to the Old French term "poque," meaning "bag" or "pouch," which itself derived from the Frankish word "pokka." The diminutive suffix "-et" was added in Middle English to signify "a small bag," evolving into the modern sense of a small compartment in clothing. The verb form emerged later, metaphorically extending the idea of "enclosing" or "taking into one's possession."
