Most people use the rising and falling inflections fairly well; they simply don't make them broad enough. Exaggerate the pitch change on the following to find a new way. In performance strive for a balance between the old and new.
Inflections.
yes
Grammar is the set of rules that defines word formation, syntax, inflections and proper usage of a language.
In some languages, yes. But not in English. All English grammatical inflections (not that there are very many of them and most of them are -s) are suffixes. Prefixes are used to change the meaning of the word not as grammatical indicators. In Swahili, on the other hand, all grammatical inflections are prefixes. Swahili does not use suffixes.
No, but they can help when the grammar is incomplete or not strictly correct. For example, the correct grammatical interrogative form is "Are you going out?" But you can convey the same meaning if you say "You are going out" with your tone rising at the end of the sentence.

Synthetic language depends primarily inflections to communicate grammatical meaning. Examples of synthetic languages are most Indo-European languages, all Kartvelian languages such as Georgian, some Semitic languages such as Arabic, and many languages of the Americas, including Navajo, Nahuatl, Mohawk and Quechua.
