Holland's last university students are boring (4)
I believe the answer is:
dull
'are boring' is the definition.
(similar in meaning)
'holland's last university students' is the wordplay.
'last' indicates one should take the final letters.
'university' becomes 'u' (abbreviation for university).
'students' becomes 'll' (an abbreviation for learner driver written twice).
The final letter of 'holland' is 'd'.
'd'+'u'+'ll'='DULL'
(Other definitions for dull that I've seen before include "Lacklustre" , "Constable?" , "Drab" , "Dreary" , "Gloomy" .)
