The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type.which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it from a true alphabet).⟨a⟩ is the third-most-commonly used letter in English (after ⟨e⟩ and ⟨t⟩), In algebra, the letter a along with other letters at the beginning of the alphabet is used to represent known quantities, whereas the letters at the end of the alphabet (x, y, z) are used to denote unknown quantities. Such associations can have a motivating effect, as exposure to the letter A has been found to improve performance, when compared with other letters.
During Roman times, there were many variant forms of the letter "A".Among these were the semicursive minuscule of Italy, the Merovingian script in France, the Visigothic script in Spain, and the Insular or Anglo-Irish semi-uncial or Anglo-Saxon majuscule of Great Britain.By the 9th century, the Caroline script, which was very similar to the present-day form, was the principal form used in book-making, before the advent of the printing press.The known variants include the early semi-uncial, the uncial, and the later semi-uncial.At the end of the Roman Empire (5th century AD), several variants of the cursive minuscule developed through Western Europe.Modern Greek orthography remains true to the historical spellings in most of these cases.As a consequence, the spellings of words in Modern Greek are often not predictable from the pronunciation alone, while the reverse mapping, from spelling to pronunciation, is usually regular and predictable.Sound values and conventional transcriptions for some of the letters differ between Ancient Greek and Modern Greek usage, because the pronunciation of Greek has changed significantly between the 5th century BC and today. The traditional orthography, which is used for Ancient Greek and sometimes for Modern Greek, has many diacritics, such as accent marks for pitch accent ("polytonic"), the breathing marks for the presence and absence of the initial In both Ancient and Modern Greek, the letters of the Greek alphabet have fairly stable and consistent symbol-to-sound mappings, making pronunciation of words largely predictable.Ancient Greek spelling was generally near-phonemic. For a number of letters, sound values differ considerably between Ancient and Modern Greek, because their pronunciation has followed a set of systematic phonological shifts that affected the language in its post-classical stages.Due to the "perishable" nature of these surfaces, there are not as many examples of this style as there are of the monumental, but there are still many surviving examples of different types of cursive, such as majuscule cursive, minuscule cursive, and semicursive minuscule.Variants also existed that were intermediate between the monumental and cursive styles.
