xo ("retroflex x"), or dontia xo ("dental x"), the phoneme can be written using prothom sô ("first s") or ditio so ("second s"), and the phoneme can be written using borgia zo ("row z" = "the z included in the five rows of stop consonants") or ontostho zo ("z situated between" = "the z that comes between the five rows of stop consonants and the row of sibilants"), depending on the standard spelling of the particular word. Assamese or Asamiya consonants include thirty three pure consonant letters in Assamese alphabet and each letter represents a single sound with an inherent vowel, the short vowel /a /. The first twenty-five consonants letters are called sporxo borno. These sporxo bornos are again divided into five borgos. Therefore, these twenty-five letters are also called borgio borno. The Assamese consonants are typically just the consonant's main pronunciation plus the inherent vowel o. The inherent vowel is assumed and not written, thus, names of most letters look identical to the letter itself (e.g. the name of the letter ঘ is itself ঘ gho). Some letters have lost their distinctive pronunciation in modern Assamese are called by a more elaborate name. For example, since the consonant phoneme /n/ can be written ন, ণ, or ঞ (depending on the spelling of the particular word), these letters are not simply called no; instead, they are called ন dointo no ("dental n"), ণ murdhoinno no ("cerebral n"), and ঞ nio. Similarly, the phoneme /x/ can be written as শ taloibbo xo ("palatal x"), ষ murdh9inno xo ("cerebral x"), or স dointo xo ("dental x"), the phoneme /s/ can be written using চ prothom so ("first s") or ছ ditio so ("second s"), and the phoneme /z/ can be written using জ borgio zo ("row z" = "the z included in the five rows of stop consonants") or য ontostho zo ("z situated between" = "the z that comes between the five rows of stop consonants and the row of sibilants"), depending on the standard spelling of the particular word. The consonants can be arranged in following groups: Group: 1 – Gutturals Group: 2 – Palatals Group: 3 – Cerebrals or Retroflex Group: 4 – Dentals Group: 5 – Labials Group: 6 – Semivowels Group: 7 – Sibilants Group: 8 – Aspirate Group: 9 – Anuxāra Group: 9 – Bixarga Group: 10 – Candrabindu (anunāsika) The letters শ (talôibbya xô),
