The letter e makes the vowel say its name
ban – block – cap – cast – cock – cod – con – cub – cut – dim – dud – fat – fin – gal – glad – her – kit – hat – hid – hop – hug – man – mat – pal – past – pin – plan – pop – pub – rap – rat – rid – Sam – slid – snack – strick – strip – tap – tim – tub – win – . . .
If you add an e to the monosyllabic words above (no matter about their meaning), you will get other English words of the English vocabulary (no matter about the different spelling and meaning) but with a different pronunciation:
ban = bane cap = cape cod = code cut = cute pin = pine e t c . . .
True, the ‘ e ‘ makes the previous vowel say its name as it sounds in the alphabet.
Good pronunciation trick that applies in most cases.
