The prefix EN- has which meaning?

The prefix EN- has which meaning?

• A. Inside
• B. Outside
• C. Between
• D. Across

Answer: (A)

Spatial prefixes in medical terms indicate location relative to another structure, and EN- means inside, within. This comes from the idea of being “in” or “within” and is seen in terms that describe inner spaces or surfaces, such as endoscope (looking inside) or endocardium (inner lining of the heart). That’s why inside is the correct meaning. Outside, between, and across are represented by other prefixes like ecto- or exo- (outside), inter- (between), and trans- (across), which don’t fit EN- in this context.
