I need to translate "only deat awaits me" into latin. The internet gave me two different options but it is very important that it is gramatically corect as it will be incorporated into a tattoo. The internet versions were 1> TANTUM MORS EXSPECTO MIHI AND 2> TANTUM LETUM EXSPECTO MIHI cAN SOMEONE PLEASE EXPLAIN THE DIFFERENCE AND WHICH IS CLOSER TO "ONLY DEATH AWAITS ME" Thank you for your help.
