In everyday spoken language, what's more stronger in meaning of "not interesting", is it "dull" or "boring"?

According to Oxford dictionary:

dull: Lacking interest or excitement.

boring: Not interesting; tedious.

N.b. can I say about a show, person, lecture, even, teacher etc, that they are dull?

Based on that, they seem to be the same or synonyms (I don't really remember when I heard dull in such context. What I used to hear is the dull as a synonym of sharp.)

  • The use of double comparatives e.g. "more stronger" is considered non-standard in English.

  • I think you were looking for the expression "more derogatory" or "Which word/term has more negative connotations?"

Both "dull" and "boring" have similar levels of intensity.

In American English, the more common and typical word is "boring".

The problem with saying a teacher is dull, is that it doesn't clearly indicate "not interesting". There is another definition of dull: "mentally slow; lacking brightness of mind; somewhat stupid; obtuse."
