"Grandfather can play."
Translation:दादा खेल सकते हैं ।
I would like to prefer "दादा जी " instead of " दादा" because it is really sounds like we are referring to the"grandfather" not the" elder brother". In India many states especially in west bengal " दादा" is refer to the "elder brother" Whenever we call our grandparents we like to put " जी" like in दादा जी , दादी जी or माँ , नाना जी , नानी जी or माँ. It is sound more respectful.
