ger.'] In gram., a short horizontal line placed 
over a, vowel to show that it is long in quantity, 
or, as in English, has a "long" sound: opposed 
to the^raie, or mark of a short vowel. Thus, in 
Greek a, T, v, and in Latin a, e, I, 6, u, the long vowels cor- 
responding to the short vowels a, e, 1, 0, a, etc. ; in English, 
a, e, i, 6, u, the conventional notations of the name-sounds

macron is used uniformly to indicate a vowel long in quan- 
tity, to the exclusion of the circumflex (except in Greek)

purpose. Thus the Anglo-Saxon and Icelandic long vow-

diphthong, as in ed, eii, etc.). Also called macrotone.
