Endings makes reference to how words end in English, it can be a suffix, 3rd person singular in present simple, adverbs, etc. I am going to explain here some of them and the most common mistakes I have seen in my students.
-th vs -ht
This ending is very easy to be pronounced but I have noticed that many students get confused maybe because they are formed by the same letters although their position is different. This is obvious and in consequence, so should be their pronunciation, shouldn’t it?? (Think about it, it’s true)
That is, the ending of the word with cannot be pronounced in the same way as the one in eight because they are not the same. (OMG!!!😊)
with -> /güiz/ eight -> /eit/
The same happens with:
both -> /bouz/ bought -> /bot/
-ED (regular past, adjectives, etc)
This pronounciation is quite difficult for Spanish speakers because it doesn’t exist in our language and it’s very complicated for us to pronounce two consonants together, as for example p and t.
To make it easier for my students, I though about a little trick that may seem crazy for many and nonsense for a language teacher, but I guess it works moreover if your level is low.
There are three different ways of pronouncing the famous -ED, it is the same whether they are verbs or other words. One of them is to pronounce it as a /t/, the second is as a /d/ and the third one is as /id/. Now, what is really difficult is to know and remember when to pronounce each one. At this moment, I ask you something: how much about phonetics do you want to learn? It is important to know how to pronounce words, but do you really want to know what a voiced, voicedless, fricative or explosive sound is? If you are a linguist ok, but i don’t think you should go so far.
As I said before, I think about something easy for my students, and here you are:
what it is important is to know which endings are pronounced /id/. Very easy, all words ending with a /t/ or /d/ sound, for example:
visit /visit/ -> visited /visitid/
interest /interest/ -> interested /interestid/
repeat /ripit/ -> repeated /ripitid/
add /ad/ -> added /adid/
head /hed/ -> headed /hedid/
Look at all verbs in the first column, they finish in a /t/ or /d/ sound.
For the rest of endings, I recommend to pronounce a /t/ or /d/ at the end of the words. There are rules, of course, to know which words are pronounced in which way, but at the beginning things should be easy. When your level improves, so will your knowledge and you will know the difference.
discovered will never be pronounced /diskoverid/ NOOOOOO!!! because it doesn’t end in a /t/ or /d/ sound but in /ə/ (?????!!!!!!) so it is pronounced /diskoverd/ (more or less, remember I don’t show real phonetics).
In this page you can learn how to pronounce each ending correctly.
And this other from the British Council is great if you want to learn sounds in English, vowels and consonants. Click on each letter to listen to how it is pronounced, repeat it and improve its pronounciation.
– Why some Spanish students say /diz/ when pronouncing did?
This is something typical Spanish.
Spaniards are used to pronouncing the ending d in syllables or words as it was a z. You may listen /Madriz/, instead of /Madrid/. I think this is a good answer for this question.
In Spanish this pronounciation isn’t correct either, but it is something quite widespread, everybody does it and it is very normal to repeat it when learning another language.
