🇬🇧
/sʌbˈspɛʃəlɪz(ə)m/
narrow specialization within a specialty
Etymology
'subspecialism' originates from Latin (via English components), specifically the prefix 'sub-' (Latin 'sub') meaning 'under, beneath' combined with 'specialism' (from English 'special' < Latin 'specialis'), where 'specialis' meant 'particular, specific'.
'special' came into English from Latin 'specialis' through Old French and Middle English; 'specialism' developed in English by adding the suffix '-ism' to 'special'. Later (mainly 20th century) the prefix 'sub-' was added to form the compound 'subspecialism' meaning a subdivision of a specialty.
Initially the elements literally suggested 'under/within a specialty'; over time the compound came to denote the modern sense of a narrowly defined area of expertise within a broader specialty (especially in medicine).
