'yawning?' is the definition.
Both the answer and definition are adjectives. Maybe there's an association between them I don't understand?

'late and one's' is the wordplay.
'late' becomes 'dead' (similar in meaning).
'and' means one lot of letters go next to another.
'one's' becomes 'tired' (I can't explain this - if you can you should give a lot more credence to this answer).
'dead'+'tired'='DEAD TIRED'
