At our school, all the "Elision" rules are "glottal-t, grosstal-stop", but we teach them all at the 3rd grade.
The reason is that if you teach strictly separately, the students will be easily confused due to the detailed rules.
Today, for those who like to study detailed rules, I will explain the rules of "glottal-t, plottal-stop" to explain the difference between the two. See the previous article for "Elision".
In this article, I will introduce what "glottal-t, plottal-stop" is.
What is glottal-t and glottal-stop?
A change in sound, also known as "glottal-t" or " glottal-stop".
In phonetics, the stop sound produced by the rapid closing of the vocal cords is called "glottic stop".
It sounds difficult to stop the glottis, but it is "to block your throat and hold your breath."
It is a short pause, done by closing the air flow in the throat (epiglottis), with no air bleeding.
I find it very difficult to explain, so I think it would be easier to understand if you explain it in words.
