The last letter changes the vowel before it
Hop has a short vowel. Hope has the same letters and an e, and the o now says what the letter is called. The e itself is not said. It marks the word as one with a long vowel.
Add an e to the end of hop and you have hope. The e is not said, but it changes the word before it: the o now says its own name. The rule is right on 131 of 140 words. The nine that break it are words you use every day, and they fall into three groups.
Core ideas
Three ideas, and the second answers a common worry.
Hop has a short vowel. Hope has the same letters and an e, and the o now says what the letter is called. The e itself is not said. It marks the word as one with a long vowel.
You might expect a rule's misses to be rare words. These are not. Have, come and some are among the commonest words in English, and give, love and move are not far behind. If you learn the rule and not the list, you will be wrong on words you meet every day.
Put an r before the final e and the rule all but stops working. The a in care does not say its name. The table scores these words apart so that they do not hide the result for all the others.
The material
Of 140 words, nine are said some other way. They are not nine separate facts.
Say hop, then say hope. The second word has one more letter, and you do not say it. What changed is the vowel: in hope the o says its own name.
That is the silent e rule. It is about words of one part, said in one beat, as hop is and hoping is not. Such a word, when it ends in a vowel, a consonant and an e, is said with the vowel's name. Bit becomes bite, tub becomes tube, mat becomes mate.
The lab takes every word of the list with one part that ends in a vowel, a consonant and an e. It leaves out words where the consonant is w, x, y or r. Then it checks the vowel against a dictionary, a book that records how words are said. That gives 140 words.
The rule is right on 131 of them, which is 93.6%. Time, make, hope, tube, huge and wide are among the words it gets right. In huge the u says you, which the table counts as the name of u.
The misses are come, have, give, lose, love, move, none, prove and some. Read the list again. These are not the words a dictionary notes as odd. They are among the words a student needs first.
Sort them and three groups appear. Have and give keep a short vowel. Come, some, love and none are said with the vowel of cup. Lose, move and prove are said with oo. Each group is small enough to say out loud in a few seconds.
There would be a tenth. The dictionary's first entry for live is the word in live music, said with the sound of eye, so the table counts it as right. The verb live, which you use far more often, has the short vowel of give. The table reads one entry and says so; your ear can add the tenth word to the first group.
English words almost never end in v. When the last sound of a word is v, an e is written after it. So the e in have is not a mark for a long vowel. It is only there so the word does not end in v. Save and wave have the same e and do follow the rule, because there the vowel is also long. The letters tell you the pattern; the dictionary tells you which of the two jobs the e is doing.
Take the words that end in a vowel, r and e. The rule says the a in care should say its name, as it does in make, and it does not. The table scores 19 of these words apart. The rule is right once, for here, which is 5.3%.
The other 18 sort the same way. Nine, among them care, rare, share, there and where, are said with the vowel of bed. Six, bore, core, more, score, shore and store, are said with the vowel of or. Two, pure and sure, have the vowel of book, and mere has the vowel of sit. An r changes the vowel before it in every way you can see here, which is why the table keeps these words apart.

Each rule reads only the letters; the dictionary says what is actually said

Method
Four steps.
The word must have one part, and its end must be a vowel, a consonant and a final e, as in make. The consonant is not w, x, y or r.
A says ay, i says the word eye, o says oh and u says oo or you. For e it says ee.
Make has one sound after the m and it is ay and then k. The last letter is only a mark.
If the word is have, give, come, some, love, none, lose, move or prove, the rule does not apply.
Here are the nine, sorted by what the vowel does instead.
The first group has a reason you can use. English spelling almost never ends a word in v, so the e in have and give is there because of the v, and not to change the vowel. The second group says one sound, the vowel in cup, though the spelling has an o. The third group has the sound oo, though o would say oh. Four words have no simple reason, and that is honest: you learn come, some, love and none as a short list.
You should be able to say what the final e does, read the score of the rule off the table, sort the nine misses into three groups, and say why the same rule fails before r.
