Category:Italian terms with unexpected vowel outcomes

Most of these fall into one of two categories:

• Proparoxytones (words with the structure [-ˈσσσ]), where some kind of modification occurred in the syllable following the stressed one, perhaps reflecting an earlier trend of vowel reduction in that position.
• A following /l/, perhaps in early Tuscan [ɫ], may have exerted a 'velarizing' influence on preceding vowels in that position.
• Adverbs where an original /-e/ has been replaced by /-i/, perhaps by analogy with those with etymological /-i/, such as ieri, fuori < Latin herī, forīs.
