The word "agnosia" in Spanish is a feminine noun.
/ˌaɡˈno.sja/
"Agnosia" is a medical term used in both written and oral contexts. It is not frequently used in everyday language, as it is a technical term mainly encountered in medical literature or formal discussions related to neurological disorders.
Since "agnosia" is a medical term, it is not commonly used in idiomatic expressions in Spanish. However, in the medical field, it can be part of discussions related to various types of agnosias, such as visual agnosia, auditory agnosia, or tactile agnosia.
The term "agnosia" comes from the Greek roots "a-" (without) and "gnosis" (knowledge), which together mean "lack of knowledge."
