A PLURAL IS MORE THAN ONE

BeCAUSE IT DOES NOT END WITH A Y S X SH CH IT IS JUST A S.

IF IT ENDS IN A SH YOU ADD ES.

IF THERE IS A Y AND THERE IS A CONSONANT BEFORE IT YOU ADD IES.

IT ENDS WITH A X YOU ADD ES.

THERE IS A CH ON THE END SO YOU PUT AN ES ON THE END.

THERE IS NO Y, CH, S, SH SO IT IS A S.

THERE IS A Y BUT IT HAS A VOWEL BEFORE IT SO IT IS JUST A S.

ThERE IS A S AT THE END SO YOU ADD ES.
