KK: /sʌbˈspɛʃəlti/
A specific area of expertise or focus within a broader field, often requiring specialized training or knowledge.
She decided to pursue a subspecialty in cardiology after completing her general medical training.
Subspecialty → It is formed from "sub-" (meaning under or below) and "specialty" (from Latin "specialitas", meaning a particular area of expertise). The word "subspecialty" refers to a specific area of specialization that is narrower than a general specialty.
Think of a field of expertise that is 'under' ('sub-') a broader area of knowledge — that's what a subspecialty means.
