expatiate
Go on extensively
To expatiate is to speak or write at length, elaborating on a subject in detail: He expatiated on the virtues of classical education.
The word carries a slightly formal or literary flavor and often implies going on longer than necessary.
Someone who expatiates doesn't just explain—they expand, digress, and thoroughly explore.
