Prolog - How do I catch an error of incorrect arity? -

not sure if question worded correctly or not, apologies. want create kind of error handling in prolog. example:

fruit(apple, pear).

now if user query:

?- fruit(x).

how inform user have made error? , homecoming message along lines of:

data should entered in format: 'fruit(x, y)' please check query , seek again.

i don't think that's application programmer's job. prolog systems has feature.

for particular case can create predicate "wrong" arity outputs message:

fruit(_) :- write('data should entered in format: \'fruit(x, y)\' please check query , seek again.'), nl, fail.
