Ay

(interjection) 1. exclamation of surprise; 'Hey!';

2. tag used at the end of a statement in order to assure that the listener is in agreement, not necessarily requiring a reply or answer, but offering the option of agreeing or disagreeing: 'Wasn't it lucky, ay?'; 'Great fun, ay?'; 'Blessing in disguise, ay'? (The usage in def. 2 is very common, and dates back to Colonial times. It is neither restricted, nor excessively more common, to New Zealand, Queensland, or any other particular region, as often claimed)
