Letters

The letters ε & υ were in prior times called εἶ & ὑ. The word simple (psilón) was appended to their names to distinguish them from the complex sounds αι & οι.
The letters ο & ω were previously called οὖ & ὦ. The words lesser (micrón) & greater (méga) were appended to their names to distinguish them from each other.
The letter σ was also called sán.
It should be known that the use of the macron (◌̄) above e & o for η & ω is a not an ancient but rather contemporary practice.

There are three additional letters only used now as numerals:

Further, the following digraphs are translated thus:

When translating names from Greek to Latin, -os is translated as -us, -ia as -y, -ion as -ium, -ros as -er, & -ōn as -o.
When translating certain sounds to Greek which it naturally doesn’t have, put τζ for gi, & τσ or σχ for ci.

More which have not digital characters yet:

The letters αυ & ευ are pronounced af & ef before a mute—e.g θ, τ—but áv & ev before a semivowel or vowel—e.g. β, α.
