Punjabi is the language of the Punjabi people and the Punjab regions of India and Pakistan.
It is an Indo-European language of the Indo-Iranian subfamily. Uniquely for an Indo-European language, Punjabi is a tonal language where the tones arose as a reinterpretation of different consonant series in terms of pitch. In terms of morphological complexity, it is an agglutinative language and words are usually ordered 'Subject Object Verb'.
The Punjabi people suffered a split between India and Pakistan during the Partition of 1947. However, Punjabi language and culture tend to be uniting factors in spite of national and religious affiliations.
