The following table contains the pronunciation of the Hebrew letters in reconstructed historical forms and dialects using the . The apostrophe-looking symbol after some letters is not a yud but a geresh. It is used for loanwords with non-native Hebrew sounds. The dot in the middle of some of the letters, called a "dagesh kal", also modifies the sounds of the letters ב, כ and פ in modern Hebrew (in some forms of Hebrew it modifies also the sounds of the letters ג, ד and/or ת; the "dagesh chazak" – orthographically indistinguishable from the "dagesh kal" – designates gemination, which today is realized only rarely – e.g. in biblical recitations or when using Arabic loanwords).
