What is the meaning of 'glottal'?

Answer 1

"glottal" refers to the space between the vocal cords and to the structures that surround that space. Those parts of the speech mechanism are known as the "glottis"; hence, "glottal." In the context of a question about English, "glottal" would refer to speech sounds that depend on the "glottis."

Answer 2

No. Dining chairs would not be a good substitute. Dining chairs are intended to be used for an hour or two, not for eight to ten hours a day. There are many styles of office chairs that will be comfortable for you to sit in all day but still be attractive. Here is an example of a very attractive chair that would also be comfortable: http://www.lampsplus.com/products/Hillsdale-Ambassador-Office-Chair__N2973.html

Answer 4

Glottal refers to sounds made by the vocal cords in the throat. It can also refer to the glottis, which is the part of the larynx where the vocal cords are located.
