Which root denotes a child?

Which root denotes a child?

• A. Pedi
• B. Ped
• C. Peda
• D. Pedia

Answer: (B)

The idea being tested is how medical terminology builds meaning from roots. For "child," the standard combining form is pedi- (or pedi). It comes from Greek pais/paidos, and you see it in terms like pediatrics, pediatrician, and pediatric. That form explicitly signals something related to children, which is why it’s the best match here. Ped-, by contrast, is typically a Latin root meaning foot and appears in words like pedal or pedestrian, so it doesn’t convey the child concept. Peda- isn’t a standard root used for “child” in medical terminology, and -pedia is a suffix or stem related to education or knowledge (as in encyclopedia), not a direct root for “child” in this context.
