Crossword Genius

Look round at an unusual leg (4)

Ross

I believe the answer is:

ogle

Here is my best explanation:

'look' is the definition.
(ogling is a kind of looking)

'round at an unusual leg' is the wordplay.
'round' becomes 'o' (round can mean a round object**).
'at' says to put letters next to each other.
'an unusual' indicates anagramming the letters.
'leg' is an anagram of 'gle'.
'o'+'gle'='OGLE'
