A macron ( ¯ ), from the Greek μακρόν (makrón), meaning "long", is a diacritic mark placed above a vowel.^[1]

Usage [change]

In the romanization of Japanese, a letter with macron represents a long vowel.^[2]

For example, in the Hepburn romanization system
- kōtsū (交通) means "traffic"
- kotsu (骨) means "bone" or "knack"

In the written Hawaiian language, the kahakō is shown by a macron.^[3]

The BGN (Board on Geographic Names) staff, under the direction and guidance of the Hawaii State Geographic Names Authority, has been restoring systemically these marks to each Hawaiian name listed in GNIS (Geographic Names Information System)"; retrieved 2012-6-16.
