   * Returns the same String value if the given value is 1 otherwise pluralises this String by appending an "s" unless
   * this String ends with "y" and not one of ["ay", "ey", "iy", "oy", "uy"] in which case the 'y' character is chopped and "ies"
   * is appended.

   * Constructs a non-empty list with the value if it is not empty, otherwise, throws an error.
