(a) Languages with more than one dialect. Some languages, for example, Chinese, have several dialects. Where a jurisdiction is obligated to provide oral assistance in such a language, the jurisdiction's obligation is to ascertain the dialects that are commonly used by members of the applicable language minority group in the jurisdiction and to provide oral assistance in such dialects. (See § 55.20.)

(b) Language minority groups having more than one language. In some jurisdictions members of an applicable language minority group speak more than one language other than English. Where a jurisdiction is obligated to provide oral assistance in the language of such a group, the jurisdiction's obligation is to ascertain the languages that are commonly used by members of that group in the jurisdiction and to provide oral assistance in such languages. (See § 55.20)
