The alphabet is a writing system which evolved from a western variety of the Greek alphabet. It was the Etruscans who first developed it after borrowing the Greek alphabet, and the Romans developed it further. The sounds of some letters changed, some letters were lost and gained and several writing styles ('hands') developed. Two such styles were combined into one script with upper and lower case letters ('capitals' and 'small letters'). Modern capital letters differ only slightly from their Roman counterparts. There are few regional variations.
