Macrocephalic

Part of speech: adjective

Definitions

1. Characterized by an abnormally large head size typically due to increased skull dimensions or brain volume, often associated with specific medical conditions or developmental abnormalities
2. Having a head that is unusually big compared to the body, usually describing a physical or pathological state marked by excessive cranial growth
3. Referring to an excessive enlargement of the cranial region, which may result from genetic, congenital, or acquired factors leading to a disproportionately large head shape

Etymology: "Macrocephalic" is a plain compound built from two Ancient Greek words: "makrós", meaning "long" or "large", and "kephalḗ", meaning "head". Put together, they describe a head that is unusually large, the same idea that the Greeks expressed in a single word for people they regarded as remarkable for their size. The word's Greek parts are combined in the same way that many modern medical and scientific terms are built, using classical roots to name a condition or feature. Its sense is literal: it describes the skull or head itself rather than any figurative quality, and it is used in medicine and anthropology to describe people or animals whose heads are notably large.

Synonyms: large-headed, big-headed

Antonyms: microcephalic, small-headed
