The first syllable contains a short vowel followed by a long (double) consonantal-i-. For the purpose of Latin scansion, this forms a long syllable. Although many dictionaries mark vowels in this context with a macron, the vowel itself is not long.[1]
‘hinc suamaiōrēs tribuisse vocābula Maiō tangor et aetātī cōnsuluisse suae.’
‘‘Because of this, theancestors granted their name to May, I have come to grasp, and in regard to their own old age.’’ (The museUrania claims that the month ofMay honors the ‘‘maiōrēs’’ – ‘‘ancestors’’ or ‘‘elders’’.)
^Nishimura, Kanehiro (2011), “Notes on Glide Treatment in Latin Orthography and Phonology:-iciō, servus, aiō”, inHistorische Sprachforschung / Historical Linguistics, volume124, page193:
It is well known that Latin orthography tends to avoid gemination of ⟨i⟩ for two successivei̯-glides [...] The most classic case may bemaior 'larger'; its phonological representation is /mai̯i̯or/ [...] the provision of a macron (i.e.,māior, as if the vowel were long) in order to display the syllable weight — the way common in a number of grammar books and dictionaries — is utterly misleading in that it disguises the phonological reality.
