'loathsome' is the definition.
(synonyms)

'outcast uplifted over penitential time' is the wordplay.
'outcast' becomes 'leper' (leper is a kind of outcast).
'uplifted' shows that the letters should be reversed in order.
'over' says to put letters next to each other.
'penitential time' becomes 'lent' (I have seen 'Time of fasting ' mean 'lent' so perhaps 'time' could also mean 'lent'. I am not sure about the 'penitential' bit.).
'leper' back-to-front is 'repel'.
'repel'+'lent'='REPELLENT'
