of a similar-sounding consonant. The vocalised forms are shown below. Like the other labiovelars, these labiovelars can only be combined with five vowels. Letters used in modern abugidas The Amharic abugida uses all the basic consonants plus the ones indicated below. Some of the Geʽez labiovelar variants are also used. The Tigrinya abugida has all the basic consonants, the Geʽez labiovelar letter variants, except for (), plus the ones indicated below. A few of the basic consonants are falling into disuse in Eritrea (as they used "ጸ" for "ፀ"). See Tigrinya language#Writing system for details. The Tigre abugida uses the basic consonants except for (), () and (ፀ). It also uses the ones indicated below. It does not use the Geʽez labiovelar letter variants. The Bilen abugida uses the basic consonants except for (), () and (ፀ). It also uses the ones indicated below and the Geʽez labiovelar letter variants. The Harari abugida uses the basic consonants except for (), (), (), (), (), and (ፀ). Although () is occasionally used, () is strongly favored. As Harari used the Arabic script before adopting the Ge'ez script, Arabic phonemes entered the language due to loanwords and language contact and were ascribed to specific consonant forms when the Ge'ez script was first adopted for the language. from () was assigned to (), from () to (), from () to (), from () to (), from () to (), from () to (), and from () to (). It also uses the ones indicated below. Note: "V" is used for words of foreign origin except for in some Gurage languages, e.g. cravat 'tie' from French. The consonant phoneme "x" is pronounced as "h" in Amharic. List order For Geʽez, Amharic, Tigrinya and Tigre, the usual sort order is called halähamä (h–l–ħ–m). Where the labiovelar variants are used, these come immediately after the basic consonant and are followed by other variants. In Tigrinya, for example, the letters based on come in this order: . In Bilen, the sorting order is slightly different. The alphabetical order is similar to that found in other South Semitic scripts, as well as in the ancient Ugaritic alphabet, which attests both the southern Semitic h-l-ħ-m order and the northern Semitic ʼ–b–g–d (abugida) order over three thousand years ago. Numerals Geʽez uses an additional alphabetic numeral system comparable to the Hebrew, Arabic abjad and Greek numerals. It differs from these
