One has no time to study there (3)
I believe the answer is:
uni
'study there' is the definition.
The definition suggests a singular noun which matches the answer.
'one has no time' is the wordplay.
'one' becomes 'unit' (synonyms).
'has no' indicates named letters should be taken away.
'time' becomes 't' (abbreviation).
'unit' with 't' taken away is 'UNI'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for uni that I've seen before include "Third-level college, in short" , "Short for university" , "College, colloquially" , "Seat of learning" , "Where you can study" .)
