思う
おもう
- middle-high (nakadaka): falls after mora 2
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).
to think, to feel
Omou has two main theories; one has it cognate with 面 (omo, “face”).

Not settled
Wiktionary itself hedges on part of this word's origin — those lines are marked below.
- “⟨omo₂pu⟩ → */əməpu/ → /omoɸu/ → /omou/”
- Hedged“From Old Japanese, from Proto-Japonic *əməp-. First attested in the Kojiki of 712 CE. Also appears in the Man'yōshū poetry compilation, completed c. 759 CE. There are two main theories for its ultimate derivation:”
- Hedged“* May be cognate with 面 (omo, “face”), from the sense of how one's emotions appear on one's face.”
- Hedged“* May be cognate with 重 (omo, “weight”), from the sense of weighing different options. Compare similar derivations of English ponder (as in “to weigh; to think”) and ponderous (as in “heavy, weighty”). However, this runs into problems, since the ancestor of this form is reconstructed as *onpo- (“heavy”).”
