Vowel length is a feature in languages when how long a vowel is spoken in a word can create a completely different word. Although this is a feature in many languages like Japanese, Arabic, Hawaiian, Classical Latin, and Thai, there are also many languages that do not have this feature.
An example of this would be the Japanese words chizu, which has a short vowel (a vowel spoken for a short time), and chīzu, which has a long vowel (a vowel spoken for a long time). The only difference that can be heard is how long the vowel "I" is spoken. The amount of time the vowel is spoken could create two entirely different words. Chizu means "map", while chīzu "cheese".
When using IPA, the colon (:) is used to show that the vowel before it is a long vowel. For example, chizu in IPA is written as /t͡ɕizɯ/, but chīzu is written as /t͡ɕi:zɯ/.
While Old English had vowel lengthening, most modern dialects of English do not. For example, the words God and good used to have the same vowel sound, but the vowel in good (/go:d/), which was a long vowel, was said longer than it was in God (/god/), which was a short vowel. Although the vowel sounds in Modern English are very different than in Old English, readers can often get an idea of how vowels used to sound like based on an English word's spelling, which often shows words' historical roots rather than their current pronunciation. Long vowels in Old English could be written with a bar on top of the vowel like in gōd (good). Later, during the days of Middle English, spellings used to spell long vowels included spelling with two vowels together like in book or break and putting a silent "E" at the end of the word like in hate. These vowels were all long vowels until the Great Vowel Shift in English, in which the vowel sounds in English changed to sound very differently from before.
Classical Latin had both vowel and consonant lengthening, and long vowels had a macron, or a straight horizontal line, written above them. In Classical Latin, ānus (/ˈaː.nus/), annus (/ˈan.nus/), and anus (/ˈan.nus/) were all different words. Ānus means "buttocks", annus means year, and anus means old woman. Today, none of the Romance languages, the languages that are daughter languages of Latin, have vowel lengthening, but Italian still has consonant lengthening.
