grill (Q20055913) - is it different from barbecue grill (Q853185)?
E.g. "мангал" ((Q|Q2374722}} is a turkish root; in Russian its corresponds to coal powered grills (barbecue grill (Q853185)) or similarly primitive grills.
I cannot say anything about "Grelha" because designs of grill can vary significantly. d1g (talk) 07:31, 1 May 2017 (UTC)
