Rudely look at reconstructed Lego (4)
I believe the answer is:
ogle
'rudely look' is the definition.
'ogle' can be an answer for 'look' (ogling is a kind of looking). I'm unsure of the 'rudely' bit.
'reconstructed lego' is the wordplay.
'reconstructed' indicates anagramming the letters.
'lego' anagrammed gives 'OGLE'.
'at' is the link.
Can you help me to learn more?
(Other definitions for ogle that I've seen before include "Stare at lecherously" , "Cast amorous glances" , "Close scrutiny" , "Gawp" , "Make eyes at" .)
