  ALA-LC Romanization table for Bengali

notes:

  - Only the vowel forms that appear at the beginning of a syllable are
    listed; the forms used for vowels following a consonant can be found in
    grammars; no distinction between the two is made in transliteration.

  - |
    The vowel a is implicit after all consonants and consonant clusters
    and is supplied in transliteration, with the following exceptions:

    a) when another vowel is indicated by its appropriate sign; and
    b) when the absence of any vowel is indicated by the subscript symbol ( ্ )
      called hasanta or birāma.

  - ব is used both as a labial and as a semivowel. When it occurs as the
    second or subsequent consonant of a consonant cluster, it is
    transliterated va. When ব is doubled, it is transliterated bba.

  - Candrabindu before guttural, palatal, cerebral, and dental occlusives
    is transliterated n̐. Before labials, sibilants, semivowels, the
    aspirate, vowels, and in final position it is transliterated m̐.

  - When doubled, abagraha is transliterated by two apostrophes ( ’’ ).
