Pronunciation: [wˌa͡ʊnd ˈʌp] (IPA) 
The phrase "wound up" is spelled with two different pronunciations of the letter "o". The first "o" is pronounced as /aʊ/ (like the "ow" in "cow"), while the second is pronounced as /ʌ/ (like the "u" in "up"). This change occurs due to a process called sound shift, where the pronunciation of a word changes over time. "Wound up" means to be tightly coiled or tense, and can also refer to being agitated or angry.
"Wound up" is a commonly used phrasal verb with multiple meanings depending on the context in which it is used. Primarily, it refers to a state of being highly agitated, distressed, or emotionally upset. In this sense, it often implies a feeling of being overwhelmed or stressed due to a specific situation or event. It can be used to describe someone who is mentally or emotionally exhausted, overly anxious, or angry. For example, if a person is constantly worried, agitated, or easily provoked, they can be described as being "wound up."
Additionally, "wound up" can also describe a state of physical tension or coiled energy. It can refer to a person being physically wound up like a tightly twisted coil, ready to release that energy at any given moment. It can be akin to a tightly wound spring that will quickly release and unwind. For instance, a person who is extremely nervous or restless, causing them to fidget or appear highly strung, can be said to be "wound up."
In another context, "wound up" can be used to describe the conclusion or final state of an event or situation. It implies the end or closure of something, often with a sense of finality or resolution. For example, if a meeting or a project reaches its deadline or comes to a conclusion, it can be said to be "wound up." In this case, it indicates the act of completing or finishing.
The phrase "wound up" has its roots in the verb "to wind". This verb, which can mean various things depending on the context, derives from the Old English word "windan" which meant "to twist or turn". Over time, the term developed additional meanings, including "to rotate" or "to coil a string". The phrase "wound up" specifically refers to the action of twisting or turning a key or handle to create tension in a spring-powered mechanism, such as a clock or a toy. Thus, "wound up" came to be associated with something that is tightly coiled or tightly wound, both literally and figuratively. In its figurative sense, "wound up" means being in a state of high tension, excitement, or agitation.
