Quick questions: javelins with dueling style and natural weapon proficiency

[Garhi]

I cannot answer a question unless the terms have been defined.

I need to know whether throw means that the object leaves the hand as it does in english or throw has some custom definition applied to it.

I am entirely unable to provide an answer to the question until the meaning of "throw" has been determined.

If your ability to answer the question relies on the definition of a specific term, you can provide the definition you are using as part of your answer. It's really not that hard.
