How to say "membrane" in Japanese
- 膜まくnounThe broad, basic word for a membrane or thin film, covering biological membranes such as cell and mucous membranes as well as thin sheets of material in general. This is usually the word you want.
- 被膜ひまくnounEmphasizes the membrane as a coating or covering enclosing something, so it suits medical or anatomical talk about protective membranes around organs. A narrower choice than 膜 rather than a free synonym.
Use 膜 for a membrane as a thin sheet of tissue or material, and 被膜 when the membrane is specifically a covering or coating wrapped around something, especially in medical or biological contexts.
