The Roman alphabet, first developed by the Etruscans and further refined by the Romans, is the foundation of many modern-day languages.
It is interesting to note that the modern Italian Alphabet consists of 21 letters, with J, K, W, X and Y not present. These ‘missing’ sounds are easily formed by joining letters together, for example, a ‘j’ sound is formed by adding the vowel ‘i’ or ‘e’ after a ‘g’, as in Buongiorno. A ‘k’ is formed by adding an ‘i’ or ‘e’ after a ‘ch’, as in the girl’s name Chiara. More can be found here.
If you don’t live in Italy and want to learn the language, a good starting point is the alphabet and the way it is pronounced. The Italian word, analfabeta means illiterate. Naturally.
