We can say "말 해 주세요" - 'Please tell me' 'Please say it'
but we do not say "어 해주세요'
We can say "말을 좀 합시다" - 'Let's talk' 'Let's have a little talk'
but we do not say "어를 좀 합시다"
Above 말 shouldn't be 어(語) but 언(言).
As trutherous said,
언(言) is the word for individual talking between persons.
어(語) is the word for generic words or languages.
Anyways we don't use neither "언 해주세요" nor "언을 좀 합시다". ^^
In some formal situations, you can see it using like...
언급(言及)해 주세요. Tell me about it, please.
언질(言質)을 주세요. Let me know your thinking, please.
첨언(添言)해 주세요. Add your opinion, please.
언어(言語) : spoken language
