I must correct something that was given by the other tutor.
مسح is the root word for مسيح
just like فعل to فعيل
one explanation given to the name
لما أنه كان عليه الصلاة والسلام إذا مسح الأكمه والأبرص عافاه الله،
Because of how he'd cure ( by the will of Allah) the blind and the leper by wiping(مسح) them
another meaning
كثرة السياحة والتنقل
traveling and journeying often
and there are other proposed reasons, including that it was am Arabization of the Hebrew word Mashih
