Which is which and what is what? 

To someone who is not familiar with grammar terminology, the main (first) section does not make it clear which of the examples are objective and which are subjective. Also, some indication as to what 'target' and 'initiator' are would be helpful. To describe things by associating them with other grammatical terminology alone, just leads people in a circle of strange new words and explains very little to those who might actually need to seek help in understanding grammatical terms by referring to a free online encyclopedia. It would be nice if someone could make this clearer and more accessible to the uninitiated. Thanks.
