1what is the basic idea behind the "yo-heave-ho" theory?a

The idea is that the sound of a person involved in physical effort could be the course of our language .a

Explanation:a

the book mentioned a lot of sources , one of these sources is the natural sounds source . Natural sound is the sounds that we usually hear or produce other than the speech . So we have to theories are included in natural sound .First " bow-wow "theory which is related to the sound we hear such as ( sounds of animal- wind-thunder…etc)so they consider this as a source .Second "yo-heave-ho" theory which is related to the sound we produce when we make some physical effort such as (Wow! > when we are amazed, Ouch! >when we have some pain, Ah! When we understand something )a

and 2. what specific type of claim is made by the"oral-gesture" theory?

For this question , actually I didn't fine the question nor the answer or anything about oral-gesture because my edition is the third one . by the way you can find all the answers for the STUDY QUESTION at the end of the book , and make sure that chapter one is included because for me, I didn't study it , we started with chapter tow, if you need any help don't hesitate
