Paediatric vs. Pediatric

  angbeenc  —  Grammar Tips

This article answers all your questions about the spelling of these two words along with definitions, origins, usage and examples. Read along and you will get to know the difference between the two spellings.


The word pediatrics and its cognates mean "healer of children"; they derive from two Greek words: παῖς (pais "child") and ἰατρός (iatros "doctor, healer").

Pediatric as a noun:

Pediatric is the branch of medicine that deals with the medical care of infants, children, and adolescents, and the age limit usually ranges from birth up to 18-21 years of age (in some places until completion of secondary education). A medical practitioner who specializes in this area is known as a pediatrician, or, a paediatrician.

Pediatric as an adjective:

Pediatric is also used as an adjective to describe something referring to the branch of medicine dealing with children and related diseases.

'The hospital's paediatric ward is under construction.'

Pediatric or paediatric:

Pediatric (without an a) is the spelling most commonly used in American English which was changed back in the 19th century, thanks to Noah Webster and his ‘theory of difference’. The original spelling of the word is 'paediatric' (with an a), which was first derived from the Greek language and is still used in all of the world except America.

So, both of the spellings are correct but the ones you choose to use depend on your area of residency, origin and audience.
