HTML <rt> Tag
Definition and Usage
The <rt> tag defines an explanation or pronunciation of characters (for East Asian typography) in a ruby annotation.
Use the <rt> tag together with the <ruby> and the <rp> tags: The <ruby> element consists of one or more characters that needs an explanation/pronunciation, and an <rt> element that gives that information, and an optional <rp> element that defines what to show for browsers that not support ruby annotations.
