The expression, according to dictionaries I referred to, is 'Play the fool.'
Do native speakers also use 'Play a fool'? One of my friends who is a native speaker says either 'a' or 'the' is fine. However, I really wonder if he is correct. If it is so, why do the dictionaries not show 'a' works too in the expression.
It's 'play the fool', not 'play a fool'.
