Program on new tablet ultimately freezes in time (14)
I believe the answer is:
apprenticeship
'time' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'program on new tablet ultimately freezes in' is the wordplay.
'program' becomes 'app' (type of computer program).
'on new' becomes 'ren' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ultimately' indicates one should take the final letters.
'freezes' becomes 'ices' (ices over).
'in' becomes 'hip' (both can mean fashionable).
The last letter of 'tablet' is 't'.
'app'+'ren'+'t'+'ices'+'hip'='APPRENTICESHIP'
Can you help me to learn more?
(Other definitions for apprenticeship that I've seen before include "Period for learning a skilled trade" , "articles" , "Training" .)
