To harp is to talk or write persistently and tediously on (a particular topic).

Example: "I don't want to harp on about the past"

Is there a similar, non-tedious equivalent?

  • Interesting. Although, one of its synonyms is dwell on. I've always took that as a negative. How about you?

To dilate: ( from TFD)

  • To speak or write at great length on a subject;

also: to tell

  • To give a detailed account of; narrate: tell what happened.

I'm not sure if it is considered entirely positive, but "gush" is a word for excitedly speaking on a subject for a time.
