Lovingly taken home, lawman's clutching a tight back (10)

'lovingly taken' is the definition.
(to be 'taken with' someone is to be infatuated)

'home lawman's clutching a tight back' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'lawman's' becomes 'deaf' (I can't justify this - if you can you should give a lot more credence to this answer).
'clutching' indicates putting letters inside.
'a tight' becomes 'taut' (I've seen this before).
'back' shows that the letters should be reversed in order.
'deaf' going around 'taut' is 'detautaf'.
'detautaf' written backwards gives 'fatuated'.
'in'+'fatuated'='INFATUATED'
