Pronunciation: [bˈɛnt nˈiːz] (IPA) 
The correct spelling of the phrase "bent knees" is /bɛnt niːz/. The first word, "bent," is spelled with a "b", "e", "n", and "t", and pronounced with the short "e" sound like in "pet." The second word, "knees," is spelled with a "k", "n", "e", and two "e"s. It is pronounced with a long "e" sound, like in "be" and a voiced "z" sound. This phrase describes a position where the knees are flexed or bent towards the body.
Bent knees refer to a physical position where the knees are not extended fully but are flexed or bent. When someone bends their knees, they are purposefully flexing the joint that connects the thigh bone (femur) to the shinbone (tibia) in the lower leg. This flexion results in the lower legs angling forward or appearing slightly diagonal when viewed from the side. Bent knees are a common natural posture adopted by individuals in various movements, such as standing, walking, running, or certain exercises.
Many activities require bent knees for optimal balance, stability, and strength. For example, in activities like squats, lunges, or jumping, intentionally bending the knees maximizes muscular efficiency, minimizes stress on the joints, and helps generate power and force. Additionally, bent knees provide a greater shock absorption capacity by distributing impact forces across the knees, minimizing strain on the joints and reducing the risk of injury.
The degree of knee flexion or how much the knees are bent can vary depending on the specific activity or purpose. It is also influenced by an individual's flexibility, strength, and comfort level. Some individuals may naturally possess hyperextended or "knock-kneed" knees, which affects the angle at which their knees bend. However, it is important to prioritize proper knee alignment and consider seeking professional advice if experiencing discomfort, pain, or limitations in knee mobility. Overall, bent knees are a commonly adopted position that allows individuals to engage in various physical movements and activities effectively.
The word "bent" comes from the Old English word "biondan", meaning "to coil, twist, or bend", which is derived from the Proto-Germanic word "bendaną". "Knees", on the other hand, originates from the Middle English word "kne", which derived from the Old English word "cnēow", both meaning "knee". The etymology of the phrase "bent knees" is then a combination of these two words, describing the action or state of having knees that are bent or flexed.
