📝 Conjugation Notes
This grammar pattern attaches directly to a noun. There are no special conjugations for the preceding noun. The following verb or noun is conjugated normally.
🔊 Pronunciation Tips
The pronunciation of 「を」 is similar to the “o” in “go.” 「もとに」 is pronounced straightforwardly as “moh-toh-nee.” The pitch accent usually falls on “も” (high) then drops “と” (low) “に” (low).
🧠 Memory Tips
Think of 「もと (moto)」 meaning “origin” or “basis.” So, 「を もとに」 literally means “taking the origin/basis,” which helps conceptualize its meaning of “based on” or “drawing from.”
