The table below gives the IPA equivalents for Latin vowels. Vowel duration varies for "short" vowels according to the number of following consonants.
|diphthongs||ae||au||ei||eu (rare)||oe||ui (rare)|
|ae, ai||aʊ||eɪ||eʊ||oe||ɰɪ when short,
uːɪ when long
I and J
In Latin, the letter written as I in ancient times was either a vowel or a consonant, depending on position and the word, the vowel being most common. The two forms had different pronunciation and different metrical treatment in poetry.
A modern typographical convention (originating in medieval scripts) is to write J for the consonant form and leave I for the vowel. This is applied both to ordinary words and proper nouns. A similar modern convention exists in writing the vowel V as U (see U and V for more). But while U is very commonly written, the use of J is more variable.
Generally speaking, modern Latin-English dictionaries always write J; for example, the substantial 1879 dictionary of Lewis and Short. Reprints of classical works on the other hand sometimes write J and sometimes write I, with the use of I being in a sense deliberately classical (though adherence to classical conventions rarely extends say to all-capitals and no spaces between words, as actually found in originals).
As a vowel,
- (Classical): IPA: short /i/, long /iː/
As a consonant,
- (Classical): /j/, but doubled /jj/ when between vowels
U and V
In Latin, the letter written as V in ancient times represented either a vowel or a consonant depending on its position and the word. These two forms had distinct pronunciations and different metrical treatment in poetry.
A modern typographical convention is to write U for the vowel and leave V as the consonant. Generally speaking dictionaries always write U this way and the majority of reprints of classical texts adapt them and show U too. The use of V for the vowel in new works is usually a deliberately classical style or appearance, and that includes for example in inscriptions on new monuments and the like.
