膝頭

1. Origins, structure, and basic meaning

• Structure: 膝頭(ひざがしら) refers to the prominent front part of the knee.
• Basic usage: It describes a specific body location, as when that part is scraped in a fall or used to support the hands.

2. Common pitfalls and similar expressions

• Combined reading
  • After 膝(ひざ), 頭 is read がしら here, producing ひざがしら.
• The knee and its front
  • Whereas 膝 broadly refers to the knee, 膝頭 focuses on its projecting front part.
  • It is an everyday location term, so a translation such as 'the front of the knee' can suit the context.
