Show pals involved in home improvements (7)
I believe the answer is:
display
'show' is the definition.
(display can mean to show or expose)
'pals involved in home improvements' is the wordplay.
'involved' indicates an anagram (involved can mean confusing or complex).
'in' indicates putting letters inside.
'home improvements' becomes 'diy' (DIY is do-it-yourself work done on the home).
'pals' anagrammed gives 'spla'.
'spla' going inside 'diy' is 'DISPLAY'.
(Other definitions for display that I've seen before include "Demonstrate, show" , "Place on show" , "Exhibit, show" , "Show to the public" , "Showcase" .)
