Lamps break around first type of screen (6)
I believe the answer is:
plasma
'type of screen' is the definition.
'plasma' can be an answer for 'screen' (I've seen this before). I am not sure about the 'type of' bit.
'lamps break around first' is the wordplay.
'break' indicates an anagram.
'around first' becomes 'a' (1st letter of 'around').
'lamps' with letters rearranged gives 'plasm'.
'plasm'+'a'='PLASMA'
Can you help me to learn more?
(Other definitions for plasma that I've seen before include "hot stuff" , "TV screen type" , "Star material" , "Ionised gas; fluid in blood" , "Screens of some TVs" .)
