Latin spelling, or Latin orthography, is the spelling of Latin words written in the scripts of all historical phases of Latin from Old Latin to the present. All scripts use the same alphabet, but conventional spellings may vary from phase to phase. The Roman alphabet, or Latin alphabet, was adapted from the Old Italic script to represent the phonemes of the Latin language. The Old Italic script had in turn been borrowed from the Greek alphabet, itself adapted from the Phoenician alphabet.
The Latin alphabet resembles most the Greek alphabet around 540 BC, as it appears on the red-figures pottery of the time.
Latin pronunciation continually evolved over the centuries, making it difficult for speakers in one era to know how Latin was spoken in prior eras. A given phoneme may be represented by different letters in different periods. This article deals primarily with modern scholarship's best reconstruction of Classical Latin's phonemes (phonology) and the pronunciation and spelling used by educated people in the late Republic and then touches upon later changes and other variants....LESS
