        Allemande Thar
        A ‘Thar Star’ is a 
formation (#20; wrong-way #21).
        ‘Thars’ and ‘Wrong Way Thars’ are ‘formations in motion’.
        
        ‘(Make an) Allemande Thar’ is a ‘suffix command’:
        it may be added to a call 
after a 
left arm turn.
        It instructs center/directed dancers to form a
        
right-hand star (#48) and back up.
        Outsides move forward, forearm hold with centers.
