Do long vowel words end with an e?

Not all!!!

The English language very rarely uses accents, to alter the stress on vowels.

In English a mute letter is inserted in to a Word to alter the stress on a vowel.

Many Words in English end in a mute letter 'e', e.g. 'like' . As spelled it is pronounced as 'l-eye-k'. However, if the 'e' was dropped to spell 'lik'. The the 'i' becomes very shorter to an 'eh' or 'ih' sound.

Some other Word.

'rot' & 'root' .
