 Early precursors of the word beryllium can be traced to many languages , including Latin <unk> ; French <unk> ; Greek <unk> , <unk> , beryl ; Prakrit <unk> ( <unk> ‌ ) ; Pāli <unk> ( <unk> ) , <unk> ( <unk> ) or <unk> ( <unk> ् ) – " to become pale " , in reference to the pale semiprecious gemstone beryl . The original source is probably the Sanskrit word <unk> ् य ( <unk> ) , which is of Dravidian origin and could be related to the name of the modern city of Belur . For about 160 years , beryllium was also known as <unk> or <unk> ( with the accompanying chemical symbol " Gl " , or " G " ) , the name coming from the Greek word for sweet : <unk> , due to the sweet taste of beryllium salts .
