plan vs intend
"plan" 強調有具體步驟或安排的打算；"intend" 則側重於主觀意圖或目的，不一定有詳細規劃。
plan vs schedule
"plan" 泛指規劃，內容可包含目標、方法等；"schedule" 特指時間表的安排。
plan vs arrange
"plan" 側重於設計藍圖；"arrange" 側重於組織、協調細節使其就緒。
在轉述他人或自己的計畫時，常用「plan on + V-ing」或「plan to」來開頭，語氣較為隨意。 EN: I plan on calling him later to discuss the details. 翻譯: 我打算晚點打給他討論細節。
EN:She plans to travel around Asia next year.
翻譯:她計畫明年去亞洲旅行。
在口語中，常加上「really」、「actually」或「definitely」等副詞來強調計畫的確定性或意外性。 EN: We really need to plan this party carefully. 翻譯: 我們真的得仔細規劃這個派對。
EN:I actually didn't plan to stay this long.
翻譯:我其實沒打算待這麼久。
思考下一步或猶豫時，會用「plan」相關的片語如「the plan is...」或「planning to...」作為填充，爭取時間。 EN: So, the plan is... we meet at the station at six. 翻譯: 所以，計畫是...我們六點在車站見。
EN:I'm planning to... maybe start a new course next month.
翻譯:我正計畫著...或許下個月開始一門新課程。
正式書寫注意：在正式報告或學術寫作中，應避免使用「plan on」這種口語結構，改用「plan to」或更正式的動詞如「intend to」、「arrange to」。口語中的填充停頓（如「the plan is...」）也應改為完整、直接的陳述。

動詞 "plan" 後面通常接不定詞 "to + 動詞原形"，表示計劃做某事，而不是接動名詞 "-ing" 形式。
×She plans buying a new car.
✓She plans on buying a new car. / She plans to buy a new car.
使用 "plan on" 時，後面必須接動名詞 "-ing" 形式。若想用 "plan" 直接接動詞，則需用 "plan to + 動詞原形"。
×Do you have a plan for go hiking?
✓Do you have a plan to go hiking? / Do you have plans for hiking?
當 "plan" 作為名詞時，表示「計劃、打算」，其後接動作有兩種常見用法：1) "plan to + 動詞原形"；2) "plan for + 動名詞/名詞"。原句混用了兩種結構。
×We are planning start the project soon.
✓We are planning to start the project soon.
進行式 "planning" 後面也必須接不定詞 "to + 動詞原形"，不能直接接動詞原形。
×The trip is still on planning.
✓The trip is still being planned. / The trip is still in the planning stages.
中文常說「在計劃中」，但英文不能直譯為 "on planning"。正確說法是使用被動語態 "being planned" 或慣用片語 "in the planning (stages)"。
×I plan him to come with us.
✓I plan for him to come with us. / I plan on him coming with us.
"Plan" 不能接「受詞 + 不定詞」的結構。若要表達「計劃讓某人做某事」，需使用 "plan for someone to do something" 或 "plan on someone doing something"。
