<abbr>

An abbreviation, with the expansion kept in the title attribute.

Without title, it only marks that something is an abbreviation. With it, the browser shows the expansion on hover, and screen readers may announce it — though support varies from one to another.

Since title does not exist on touch, the good practice is still to write the expansion out on first appearance and reserve the element for later ones.
