   Note

   Talk is what this sense usually describes: an argument, a discussion, a row, an exchange. It grades freely, so a debate can grow more heated or be the most heated of the evening. That is a quick way to tell it from the literal "warmed" meaning, which rarely takes more or most. The image comes from the verb heat, which can also mean to inflame the passions.

3. 3
   verb

   Simple past and past participle of heat.

   The blacksmith heated the iron until it glowed red.

   We heated the leftover stew for dinner.

   Note

   A regular -ed form, though the verb once had another: in obsolete dialect use, heat itself served as its own past tense. Today heated does both jobs, as in the blacksmith heated the iron and the iron was heated. It often pairs with up when food or a room is being warmed, as in we heated up the soup.
