The primitive root.
Strong’s H4899, mashiyach, a concrete noun meaning, “Anointed One,” that is, Messiah; from Strong’s H4886 משח mashach, a primitive root meaning, “to anoint,” that is, to smear with oil. The 3-letter root is mem + shin + chet.
mem מ, ם = the water, thus chaos, mighty, blood
shin ש = two front teeth, thus sharp, press, eat, two, again
chet ח = the wall, thus outside, divide, half

Ointments were made from oils and smeared on injuries for healing. Oil was also smeared on the heads of individuals who are being given the office of a prophet, priest or king as a sign of authority. – Ancient Hebrew Lexicon
And being in Bethany at the house of Simon the leper, as He sat at the table, a woman came having an alabaster flask of very costly oil of spikenard. Then she broke the flask and poured it on His head. Mar 14:3
