In historical linguistics, metaphony is a general term for a class of sound change in which one vowel in a word is influenced by another in a process of assimilation.
Progressive metaphony, in which a vowel early in the word influences a subsequent vowel, can be distinguished from regressive metaphony, in which a vowel towards the end of the word influences a preceding vowel. (Progressive metaphony is sometimes called "left-to-right" metaphony, and regressive metaphony may be called "right-to-left" metaphony.)
Progressive metaphony is also called vowel harmony, and is discussed fully in the article under that heading. However, some linguists use the term "vowel harmony" for regressive metaphony too.
Examples of regressive metaphony are i-mutation and a-mutation. (On i-mutation in Germanic languages see also Germanic umlaut.)
In the Romance languages, metaphony was an early vowel mutation process that operated in all Romance languages to varying degrees, raising (or sometimes diphthongizing) certain stressed vowels in words with a final /i/ or /u/ or a directly following /j/. This is conceptually similar to the umlaut process so characteristic of the Germanic languages. Metaphony is most extensive in the Italo-Romance languages, and applies to nearly all languages of Italy. However, it is absent from Tuscan, and hence from standard Italian.
Metaphony in the southern Italian languages (those to the south of Tuscany) is triggered by final /i/ and /u/. High-mid vowels /e o/ are raised to /i u/, and low-mid vowels /ɛ ɔ/ are either raised to /e o/ or diphthongized to /je wo/. Metaphony is not triggered by final /o/. The main occurrences of final /i/ are as follows:
Lend me your children to borrow
I just need to send them away
Long eyes and tears of sorrow
I promise I'll keep them safe
So sorry it didn't work out
You believed the liar in me
My God, my love, my life
My world, my loss, my rage
Agnostic for the greater good
When the good things seem to be few and far between
Conscious loss of conscience
Packed the body on ice just to keep it numb
No feeling
Blame some things on the past
Threw away everything that I had
Unraveling for the last time
Stepping out of my skin cast in armor
The hate in me, feeling so empty
The guilt I swallow
Carve the line, skin the face
Stare through me
We'll leave you hollow, hollow
Assembly of the militant
What are you in our game?
Eradicate the power's law
Hope's a thing of the past
[Incomprehensible]
The hammer falls
The hate in me, feeling so empty
The guilt I swallow
Carve the line, skin the face
Stare through me
We'll leave you hollow
Wounded, having a loss of feeling
So dead my heart, my life has been ruined
Lost in an instant, saw red in my eyes
The hate in me, so consuming
The lives we swallow
To the front line, mirror's engaged
Scope's on me and leaves me hollow
Harvest children, harvest children
Harvest children, harvest children
Harvest children
My God, my love, my life
