We are all aware of the famous phrase, check mate!
It is when the king has been cornered to its inevitable death.
In Arabic, a king is pronounced as مَالِك (Mālik). However, in numerous cases respect given to someone is used by the term شَيْخ (Shaykh). Generally, it means someone who is knowledgeable, over the age of 50, or someone highly respected within the community. So at times referring to a king as Shaykh in not inappropriate.
When looking into the etymology of Check Mate, it actually comes from Persian, which has Arabic origins, meaning شَيْخ مَاتَ (Shaykh Māt), meaning the Shaykh has died.
