The word 'vexed' has a journey rooted in physical agitation. Its core, 'vex', descends from the Latin verb vexare, which meant 'to shake violently, harass, or trouble'. This Latin term itself is an intensive form of vehere ('to carry'), suggesting a sense of being carried away or tossed about. Over time, the meaning softened from literal, physical disturbance to the figurative agitation of the mind or feelings. The addition of the common English adjectival suffix '-ed' solidifies its role in describing the resulting state—someone who is annoyed or a problem that is persistently troubling and unsettled.

Structure: vex (to annoy) + ed (adjective suffix) 'vex' originates from Latin vexare meaning 'to shake, disturb, annoy'. The suffix '-ed' is from Old English '-ed', '-od', '-ad', used to form adjectives from verbs, indicating a state or condition.
