Thank you for answering the threads I posted in.
Now, i want to know in details differences between sentence(written English) and utterance(spoken English).I am preparing to post a term-paper about these.So,let me know about these widely.For example,differences in style or grammar .
With great expectation,
an active learner
Utterance is the noun form of utter (verb), which means to speak or say. So an utterance can be any vocally produced sound -- it doesn't even have to be a word. Technically, a burp could be considered an utterance.
A sentence (in the context you mean) can be written or spoken. It's simply a group of words that expresses a complete thought or idea. Sentences typically contain a subject and a predicate containing a verb.
I'm not sure if that answers your question, but hopefully it helps!
