Spades taken out of the case for undesirable digs (5)
I believe the answer is:
hovel
'spades taken out of the case for undesirable digs' is the definition.
I can't tell whether this defines the answer.
'taken out of the case for undesirable digs' is the wordplay.
'taken' becomes 'held' ('hold' can be a synonym of 'take').
'out of' means to remove the last letter (I've seen 'out' mean this).
'the case for' is an insertion indicator.
'undesirable digs' becomes 'ov' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'held' with its last letter taken off is 'hel'.
'hel' placed around 'ov' is 'HOVEL'.
Can you help me to learn more?
(Other definitions for hovel that I've seen before include "Ramshackle dwelling" , "Dirty, neglected dwelling" , "Crude dwelling" , "Shanty; hut" , "Small crude shelter" .)
