昔
むかし
- flat (heiban)
How to read it: a line over a kana means the voice is high there, and ↓ marks where it drops. A kana with no line is low. With no ↓ the pitch stays high to the end and does not drop even on a following particle (が, は).
old days; past
Mukashi is muka, from the verb 向く (muku, “to face opposite”), plus a direction suffix し (shi): “that which stands opposite from the present”.

Not settled
Wiktionary itself hedges on part of this word's origin — those lines are marked below.
- Hedged“From Old Japanese. The muka portion derives from the 未然形 (mizenkei, “incomplete form”) of verb 向く (muku, “to face opposite to something”), implying “that which stands opposite from the present”. The shi portion is suffix し (shi) indicating direction, also found in words 縦し (tatashi, “the standing or vertical direction”), 横し (yokoshi, “the sideways or horizontal direction”). This appears to be a somewhat rare alternative form, more commonly encountered as さ (sa), and may be cognate with the nominalizing adjective ending さ (sa).”
