Specialist lexis
Specialized vocabulary or terminology associated with particular fields, professions, or domains of knowledge. Specialist lexis enables precise technical communication.
Real World
When Elon Musk discusses rocket engineering, he uses specialist lexis like 'specific impulse', 'thrust vectoring', and 'payload fairing' — terms that communicate precisely within the aerospace community but exclude lay audiences.
Exam Focus
Always comment on the effect of specialist lexis on audience — whether it includes, excludes, or establishes authority — to hit the higher mark bands.
