Choosing を, へ, と and も by sentence role
Identify objects, routes, direction, co-participants and quotation instead of translating one word.
Distinguish an object from a route
本 in 「本を読みます」is an object; 公園 in 「公園を散歩します」marks a traversed place. Compare 「学校で勉強します」, where で gives the action location. Inspect the predicate and role of the place rather than choosing a particle solely because the noun is a location.
Separate direction, companionship and quotation
「駅へ行きます」highlights direction; 「駅に行きます」can name the destination. They overlap in common movement statements, but not every に becomes へ. と names a co-participant in 「友達と話します」and introduces quoted content in 「友達が来たと言いました」. Identify what is being quoted before と.
Check the role retained with も
「私も行きます」adds another participant, while 「学校にも行きます」retains the role of に and adds that destination. Compare learned examples rather than assume も replaces every particle. Mark participant, place and quotation scope before changing information.
Example
Original contrast: 「友達と公園を散歩します。」marks companion and route; 「公園で友達と話します。」marks the action location and companion.
Check your understanding
Explain why the place particles differ in the two sentences.
Explanation
The park is traversed in walking and is the location of talking. Explain the predicate and role together.

- Why does walking use 公園を while studying uses 学校で? What roles do these places have?
- Going to a station can use ni or e. How should I choose in a beginner response?
- Does to have the same function in talking with a friend and quoting that a friend arrived?
- Does mo replace wa or follow other particles? How can a beginner check combinations?
