Abjads, or consonant alphabets, represent consonants only, or consonants plus some vowels. Full vowel indication (vocalisation) can be added, usually by means of diacritics, but this is not usualy done. Most of abjads, with the exception of Ugaritic, are written from right to left.
Some scripts, such as Arabic, are used both as an abjad and as an alphabet.
