https://developer.mozilla.org/en-US/docs/Web/HTML/Element/abbr Testcase: http://jsfiddle.net/TheDJ/768y7npt/ At the very least I would expect Safari+VO, when it settles on the element, to read the title= content, like it does for other elements. Even better would be if it would pronounce something like: "Abbreviation: HTML for Hyper Text Markup Language" on the very first time it would encounter the abbreviation. Currently it does neither.

Rechecked this 7,5 years later, macOS 13.0.1 and Safari 16.1 unfortunately still do not support the abbr. tag.
This too seems to work now in Safari 17 with macOS 14. https://developer.mozilla.org/en-US/docs/Web/HTML/Element/abbr Ashok's joke made me <abbr title="Laughing out loud">LOL</abbr> big time. is now read by VO and Safari as: Ashok's joke made me LOL big time. Laughing out loud, big time.
Nvmd. false hope. It seems LOL is some sort of hard coded value in VoiceOver, just as no. is.
