errors.add adds "is invalid" if validation fails

Rails, I have problem.

I am validating fields of a class, if validation fails i use the
method error.add "Say something" , but when I test my form by giving a
invalid entry, I get error output as "Say something is invalid" and
not as "Say something". I really dont know where from this "is
invalid" pops in. Any help?

Thanks in advance

tru this and reply:
errors.add(:field, 'Say something')
errors.add_to_base('Say something')

Thanks
