Major Influencer
Greek is a significant influence in other languages because so many words have roots in either Greek or Latin, particularly in English. It’s still used today to help ease the creation of new words. The word Alphabet comes from the first two letters of the Greek alphabet, “alpha” and “beta”. Approximately 12 percent of all English words come from Greek. English has had some influence on Greek too. Their words for freak out and glamour are like that of English.

Two Greeks
Until the year 1976, there were actually two versions of Greek on record as official languages. Demotic was used for casual conversation and literature. Academia, law, medicine, and newspapers all used Katharevousa. The government designated Demotic Greek as its official language after that year.
