The word "peaked" is spelled with the letters p-e-a-k-e-d. In IPA phonetic transcription, it is pronounced /piːkt/. The "ea" in "peaked" is pronounced with a long "e" sound, as in the word "bee".

"Peaked" can be used to describe something that has reached its highest point or has a sharp, pointed shape.
Peaked is an adjective that describes a state or condition of something or someone that has reached its highest point or pinnacle, often in terms of physical health or performance. When applied to a person, it refers to someone who is at the height of their abilities, or someone who is experiencing the prime of their life. However, when describing physical health, peaked typically indicates a state of decline or deterioration.
In terms of physical health, a person is often considered to be peaked when they are at the lowest point of their wellness. This could include showing signs of illness, weakness, fatigue, or even a significant decline in energy levels. Similarly, when referring to a performance or achievement, peaked signifies that the individual or subject has reached their maximum potential or highest level of success and is unlikely to improve further.
The term may also be used to describe an object or situation that has reached its climax or pinnacle of development. For example, a peaked mountain signifies the highest or most prominent peak in a range, while a peaked interest suggests that interest or curiosity has reached its highest point and is likely to wane.
Overall, peaked describes the condition or state of something or someone at its highest or lowest point, whether it be physical health, performance, achievement, or even interest. It often implies a sense of culmination or decline, depending on the context in which it is used.

The word "peaked" has two different etymologies, depending on its usage.
1. When used to mean "having a sharp or pointed top", "peaked" derives from the Old English word "pec", meaning a sharp point or hilltop. This Old English root is related to the Old High German word "spitza", which means "sharp point" or "peak".
2. When used to mean "unhealthy or ill-looking", "peaked" comes from the Middle English word "pek", which means "to cut short" or "to become weakened". This Middle English verb is believed to be derived from the Old Norse word "bekkr", meaning "bench" or "seat". Over time, the word "pek" came to be associated with the idea of being weakened or diminished in appearance, which eventually evolved into its current sense of looking unwell or pale.
