The V(owel)-C(onsonant)-silent "e" Rule

One of the most frustrating features of English is pronunciation because it isn't clearly related to spelling. There doesn't seem to be any logic to spelling and pronunciation - no matter if you're a native speaker or a non-native speaker of English. So, are there any rules that we teachers can pass on to our students about how to say unfamiliar words?

The simplest rule that most native speakers follow - even if they don't consciously know it's a rule - is the (V)owel - (C)onsonant - Silent ("e") pronunciation pattern V-C-e at the end of a word.  The easiest way to illustrate is with words: gate, late, mate, state, fate, date, rate, relate, debate and so on. In these words, the "a" in the "-ate" part sounds like [e] in the phonetic alphabet, "e" sounds like [i], "i" sounds like [ay], "o" like [oʊ], and "u" like [yu], with a "y" sound in front of the "u", as in "cute" [kyut] or without the "y" sound, as in "dude" [dud] or "flute" [flut].

As you can see, there are a lot more words ending in -aCe, -iCe, -oCe, and -uCe than -eCe.  I suspect that that probably means there are alternate spellings for the long "e" sound in English. And, of course, remember that the above "rule" (V-C-e) is only a rule of thumb.  In other words, there are several exceptions to the rule, such as the irregular past participles, done and gone, whose "o's" are pronounced differently in each word and differently from lone, which does follow the rule.
