In Sri Lanka, the term 'Sinha' (or Siha / Sinhe / Singhe / Singha / Singho) have commonly been used by the Sinhalese (or Sinhala). When it comes to the term 'Sinhala' itself, the first part of the word, 'Sinha' stands for lion while 'la' or 'le' stands for blood, giving the meaning 'Lion's blood'. The word Simhmam (or Singam / Singham / Singhai / Singai) is the Sri Lankan Tamil derivative. In northeast India, Sinha's held high positions as advisors during the times of the Mughal Empire.
