What does expatiator mean?
An expatiator is a person who speaks or writes at length, ranging freely across topics and digressions rather than coming briskly to the point. The word derives from the verb 'expatiate', which comes from Latin 'expatiari', meaning to wander or spread out beyond bounds — so an expatiator is, literally, one whose discourse wanders abroad. The term is rare and distinctly formal or literary in register, and it usually carries a gently mocking edge: it suggests garrulousness and self-indulgence rather than eloquence. Yet it can also be deployed affectionately, even admiringly, of a raconteur whose meanderings are part of the pleasure. English more often uses the related forms 'expatiate' ('to dwell at length on a subject') and 'expatiation' (the act of doing so); 'expatiator' itself appears chiefly in polished prose describing conversationalists, lecturers, and writers who cannot resist elaboration. It should not be confused with 'expatriate' or 'expiator', which differ entirely in meaning.
nounA person who speaks or writes at length, especially in a rambling or discursive manner; someone given to expatiation.

"The memoirist is less a storyteller than an expatiator, lingering over every detour her memory offers."
Standard regular plural; used when referring to multiple habitual ramblers.
"The seminar attracted expatiators from every department, each determined to have the last word."
An expatiator never gives a one-word answer — the word itself comes from Latin for 'to wander out', as if speech were a journey with no planned return.

Etymology of expatiator
Expatiator derives from the verb 'expatiate', from Latin 'expatiari' — formed from 'ex-' ('out') plus 'spatiari' ('to walk about'), itself rooted in 'spatium', the source of English 'space'. In English, 'expatiate' came to mean both to roam physically and, more durably, to range widely or at length in speech and writing. 'Expatiator' is the straightforward agentive formation from that verb, denoting one who expatiates, and has been used in English since roughly the seventeenth century alongside cognates such as 'expatiation'. Its closest kin are the other 'spatium'-derived words like 'spatial' and 'expansive'.
How expatiator is actually used
Rare and markedly formal or literary; it typically carries a mildly pejorative connotation of long-windedness, though it can be used affectionately or admiringly of a gifted talker. The agentive verb 'expatiate' and noun 'expatiation' are considerably more common.
