| 119 ;; Syllable ::= Cons-Vowel-Syllable | Vowel-Syllable | |

| 125 ;; | |
| 126 ;; {} repeat, [] optional | |

| 139 ;; In Emacs, one syllable of Indian language is considered to be one | |
| 140 ;; composite glyph. If we expand the above expression for | |
| 141 ;; cons-vowel-syllable, it would be: | |
| 142 ;; | |
| 143 ;; [[C [N] H] [C [N] H] [C [N] H] C [N] H] C [N] [M] [D] | |
| 144 ;; | |
| 145 ;; Therefore, in worst case, the one syllable may contain | |
| 146 ;; following characters. | |
| 147 ;; | |
| 148 ;; C N H C N H C N H C N H C N M D | |
| 149 ;; | |
| 150 ;; The example is a sanskrit word "kArtsnya", where five consecutive | |
| 151 ;; consonants appear. | |
| 152 ;; | |
| 153 ;; On the other hand, consonant-syllable, which appears at the end of | |
| 154 ;; the word, would have the following expression: | |
| 155 ;; | |
| 156 ;; [C [N] H] [C [N] H] [C [N] H] C [N] H | |
| 157 ;; | |
| 158 ;; This is acceptable BEFORE proper consonant-syllable is input. The | |
| 159 ;; string which doesn't match with the above expression is invalid and | |
| 160 ;; thus must be fixed. | |
| 161 ;; | |
| 162 ;; Note: | |
| 163 ;; Third case can be considered, which is an acceptable syllable and can | |
| 164 ;; not add any code more. | |
| 165 ;; | |
| 166 ;; [[C [N] H] [C [N] H] [C [N] H] C [N] H] C [N] [M] D | |
