Endings -e/-es

[undeddy]

When are they pronounced like /iz/, when like /s/ (maybe there is also a variant /is/)?

Dear Undeddy:

Words that end in -x (fox), -ch (church), -sh (wash), -ss (toss), -zz (jazz), -ce (piece), -se (purse), -ge (page) have the audible -es plural.

Most everything else is just /s/.

This is an 'off the top of my head' list. If I've left anything out, I'm sure another teacher will jump in to complete/correct my response.

So, you mean that if a word has on of the listed endings, it is pronounced like /iz/.

But how is a word pronounced if its ending is a
1) vowel: for example, opportunity -> opportunities /iz/ or/is/ ?
2) voiced consonants like /l, n,m d etc/: for example, apple -> apples /z/ or /s/

I'm also interested how the comparative forms of the following words are pronounced: long (->longer /lɒŋgə/ or /lɒŋə), strong, young etc
So, is there the sound /g/ in the comparative forms of such words?

Thanks beforehand.
