Shabash: well done. The Rekhta dictionary describes it in Hindi as a word of praise that encourages and raises courage. Its example: Shabash, bete, tumne itna achchha match khela ki aaj ji khush kar diya. Well done, son. You played such a good match that you made me happy today.
Mehnati: hardworking. Rekhta gives “hard worker, hard-working, laborious, industrious, diligent.”
