Silent e pattern

Sam remains "Same" :)

Logic

When E sits at the end of the word - it stays silent, but makes the vowel preceding the consonant Long Vowel.

When?

To create a long vowel, there is usually only one consonant between the silent ⟨e⟩ and the preceding vowel. In some cases two consonants may also have the same effect, as in table, paste and bathe, while in other cases no consonants are found, as in tie, toe and due.

History

This pattern is a leftover from Middle English. Hundreds of years ago, that final e wasn't silent—it was actually pronounced as a soft "uh" sound (schwa). Over time, English speakers stopped pronouncing the final e, but the vowel before it stayed stretched out and long.

Words with dg before e

Silent ⟨e⟩ is used in some words with ⟨dg⟩ in which it does not lengthen a vowel: rĭdgɇ, slĕdgɇ, hŏdgɇ-pŏdgɇ. Spelling such words with ⟨j⟩, the other letter that indicates that sound, does not occur in native or nativized English words.

Words with truly silent e

In some words, the e is truly silent and does not affects the pronunciation of the vowels before it.
This is common for Intervocalic Voicing of F to V.

Word IPA Expected if Magic e Worked Actual Vowel Why the Silent e?
give /ɡɪv/ */ɡaɪv/ Short /ɪ/ English words do not end in bare v; e is orthographic only.
live (verb) /lɪv/ */laɪv/ Short /ɪ/ Final e follows the spelling rule after v.
love /lʌv/ */loʊv/ Short /ʌ/ Silent e does not lengthen the vowel.
have /hæv/ */heɪv/ Short /æ/ Final e is required after v.
above /əˈbʌv/ */əˈboʊv/ Short /ʌ/ Final e retained after v.
glove /ɡlʌv/ */ɡloʊv/ Short /ʌ/ Silent e is orthographic only.
dove (bird) /dʌv/ */doʊv/ Short /ʌ/ Exception to the usual magic-e rule.
shove /ʃʌv/ */ʃoʊv/ Short /ʌ/ Silent e follows v, not the vowel.
move* /muːv/ Long /uː/ Here the vowel is long for historical reasons, not because of the silent e.

How to show when final-e is non-silent?

Affecting Consonants

An example with consonants is the word-pair loath (loʊθ) and loathe (loʊð), where the ⟨e⟩ can be understood as a marker of a voiced ⟨th⟩.

Silent e making C and G soft when after it
