'stay' is the definition.

'over with dirty lecturer' is the wordplay.
'over' is a reversal indicator.
'with dirty' becomes 'lewd' (similar in meaning. I am not sure about the 'with' bit.).
'lecturer' becomes 'l' (abbreviation for lecturer).
'lewd' in reverse letter order is 'dwel'.
'dwel'+'l'='DWELL'
