Erro comum:
Learners sometimes confuse “membrane” with “member” because they look similar. “Membrane” is always about a thin layer (usually in the body or in science), while “member” means a person in a group or a part of a body (like a limb). Another mistake is to use “skin” instead of “membrane” in technical or medical contexts where the more precise biological term is needed.

Erro comum:
Learners may use “layer” or “sheet” instead of “membrane” in technical descriptions. While often understandable, “membrane” is preferred when the layer is very thin and used to separate or filter substances, especially in engineering or chemistry.

Sinónimos
film (Emphasizes thinness but not necessarily the selective barrier or filtering function that “membrane” often implies.)
|
barrier layer (Highlights the blocking or separating role, but does not suggest flexibility or controlled passage as clearly as “membrane.”)
Antónimos
open passage (An open passage allows free movement without a separating layer, the opposite of what a membrane provides.)
