Stare at a legendary giant with a broken leg (6)
I believe the answer is:
goggle
'stare at' is the definition.
(thesaurus)
'a legendary giant with a broken leg' is the wordplay.
'a legendary giant' becomes 'gog' (I've seen this before. I am not sure about the 'legendary' bit.).
'with' is a charade indicator (letters next to each other).
'a broken' indicates anagramming the letters.
'leg' is an anagram of 'gle'.
'gog'+'gle'='GOGGLE'
Can you help me to learn more?
(Other definitions for goggle that I've seen before include "Hit, beat (archaic)" , "Stare wide-eyed in amazement" , "Look in amazement with wide open eyes" , "wonder" .)
