5.2 Purpose, Intention & Readiness (〜ように/ために, 〜ようとする, 〜向け/向き, 〜ついでに)

5.2 Purpose, Intention & Readiness (目的・意図・準備・方向性)

Expressing purposeful human action in Japanese requires navigating a refined network of grammatical structures that encode intentionality, volitionality (ishi vs. mu-ishi), aspectual readiness, and targeted design. While English frequently relies on generic infinitives ("in order to", "so that", "aimed at"), Japanese enforces strict syntactic and semantic boundaries depending on whether an action is fully controllable by the speaker, directed toward an indirect non-volitional state, situated on the immediate verge of happening, or tailored for a specific audience.

In this section, we master four cornerstone grammar complexes of the JLPT N3:

1. The Classic Purpose Duel: 〜ために (tame ni) vs. 〜ように (yō ni)
2. Immediate Brink, Attempt & Refusal: 〜ようとする / 〜ようとしない (yō to suru / yō to shinai)
3. Targeted Design vs. Inherent Suitability: 〜向け (muke) vs. 〜向き (muki)
4. Opportunistic Secondary Action: 〜ついでに (tsuide ni)

1. The Definitive Battle: 〜ために vs. 〜ように

No grammar distinction appears more frequently in the JLPT N3 than the contrast between 〜ために (tame ni) and 〜ように (yō ni). While both translate broadly as "in order to" or "so that", their underlying syntactic constraints and semantic mechanics are diametrically opposed.

Detailed Breakdown: 〜ために (Direct Volitional Goal)

• Semantic Core: Indicates a conscious, deliberate objective that the subject actively controls. Clause 2 contains an intentional, volitional action executed specifically to achieve Clause 1.
• Grammatical Constraints:
  1. The verb preceding ために must be a volitional verb in the dictionary form (辞書形).
  2. The subject of Clause 1 and Clause 2 must be identical.
  3. It cannot take potential verbs (kanō dōshi), intransitive state verbs, or negative verbs.
  4. Noun connection takes the genitive particle: Noun + のために.

Exemplary Sentences:

• 自分の店を持つために、毎月必死にお金を貯めている。<br>Jibun no mise o motsu tame ni, maitsuki hisshi ni okane o tamete iru.<br>(In order to have my own shop, I am desperately saving money every month.)
• 健康を維持するために、毎朝ジョギングを欠かさない。<br>Kenkō o iji suru tame ni, maiasa jogingu o kakasanai.<br>(In order to maintain my health, I never skip jogging every morning.)
• 留学のために、パスポートとビザを申請した。<br>Ryūgaku no tame ni, pasupōto to biza o shinsei shita.<br>(For the purpose of studying abroad, I applied for a passport and visa.)

Detailed Breakdown: 〜ように (Indirect Desired State or Negative Goal)

• Semantic Core: Indicates aiming for a certain condition, capability, or natural outcome that is not directly controllable by pure immediate willpower. Clause 2 represents an effort made so that a non-volitional state in Clause 1 can naturally materialize.
• Grammatical Constraints:
  1. Preceded by Non-Volitional Verbs (無意志動詞): Intransitive change verbs such as 分かる (understand), 見える (be visible), 聞こえる (be audible), 治る (heal/recover), 届く (reach), 間に合う (be in time).
  2. Preceded by Potential Verbs (可能動詞): e.g., 話せる (can speak), 合格できる (can pass), 読める (can read).
  3. Preceded by Negative Verbs (〜ないように): Meaning "so that X does not happen / to avoid X".
  4. Different Subjects Allowed: The subject of Clause 1 can be different from Clause 2 (e.g., Parent acts so that Child can study).

Exemplary Sentences:

• 後ろの席の人にもよく聞こえるように、大きな声で話してください。<br>Ushiro no seki no hito ni mo yoku kikoeru yō ni, ōkina koe de hanashite kudasai.<br>(Please speak in a loud voice so that people in the back seats can hear clearly. — kikoeru is non-volitional)
• 風邪をひかないように、暖かい格好をして出かけた。<br>Kaze o hikanai yō ni, atatakai kakkō o shite dekaketa.<br>(I went out dressed warmly so that I wouldn't catch a cold. — negative prevention)
• 日本の新聞が読めるように、毎日漢字を20個ずつ覚えている。<br>Nihon no shinbun ga yomeru yō ni, mainichi kanji o nijukko zutsu oboete iru.<br>(I memorize 20 kanji every day so that I can read Japanese newspapers. — potential verb yomeru)
• 子どもが一人で起きられるように、目覚まし時計を買ってやった。<br>Kodomo ga hitori de okirareru yō ni, mezamashidokei o katte yatta.<br>(I bought an alarm clock for my child so that they could wake up by themselves. — different subjects: parent buys, child wakes up)

The Direct Pair Comparison

Notice how the verb form dictates the entire grammar choice:

• ❌ 日本語を上達するために勉強する → Incorrect! (上達する is an intransitive state change)
• ⭕️ 日本語が上達するように勉強する → Correct! (Aiming for a state of proficiency)
• ❌ 車を運転できるために練習する → Incorrect! (Potential verb cannot take ために)
• ⭕️ 車を運転できるように練習する → Correct! (Aiming for acquired capability)
• ⭕️ 車を買うために貯金する → Correct! (Buying a car is a direct volitional action)

2. On the Brink, Attempt & Refusal: 〜ようとする / 〜ようとしない

Morphological Formation

This construction pairs the Volitional Form (意向形, ikōkei) of a verb with the auxiliary verb とする (to suru):

• Group 1 (五段): 行く → 行こうとする, 書く → 書こうとする, 飲む → 飲もうとする
• Group 2 (一段): 食べる → 食べようとする, 降りる → 降りようとする
• Group 3 (不規則): する → しようとする, 来る → 来ようとする (koyō to suru)

│ 3. Obstinate Neg.│ 〜ようとしない       │ "Refuses to / zero effort"   │
└──────────────────┴──────────────────────┴──────────────────────────────┘

Usage 1: Immediate Temporal Brink (まさに〜する直前)

• Nuance: Indicates that an event or interruption suddenly occurred at the absolute split-second when the subject was poised to perform an action.
• Typical Connectors: 〜ようとしたとき, 〜ようとしたら, 〜ようとしたところに.
• Example: 家を出ようとしたとき、急に激しい雨が降り出した。<br>Ie o deyō to shita toki, kyū ni hageshii ame ga furidashita.<br>(Just as I was about to leave the house, heavy rain suddenly began pouring down.)
• Example: 電車に乗ろうとしたら、目の前でドアが閉まってしまった。<br>Densha ni norō to shitara, me no mae de doa ga shimatte shimatta.<br>(Right when I was about to board the train, the doors closed right in front of my eyes.)

Usage 2: Physical or Mental Attempt (試み・努力の最中)

• Nuance: The subject is actively making a physical effort or struggling to accomplish something challenging.
• Example: 生後10か月の赤ちゃんが、一人で立ち上がろうとしている。<br>Seigo jikkagetsu no akachan ga, hitori de tachiagarō to shite iru.<br>(The 10-month-old baby is trying to stand up on its own.)
• Example: 必死に思い出そうとしたが、どうしても彼の名前が出てこなかった。<br>Hisshi ni omoidasō to shita ga, dōshitemo kare no namae ga detekonakatta.<br>(I tried desperately to recall, but his name just wouldn't come to mind.)

Usage 3: Third-Person Refusal & Complete Lack of Will: 〜ようとしない

• Nuance: Used primarily for a third party who shows utter stubbornness, active refusal, or complete disinterest in doing something they clearly ought to do ("makes no attempt to / refuses to").
• Example: 息子は注意されても、自分の非を認めようとしない。<br>Musuko wa chūi saretemo, jibun no hi o mitomeyō to shinai.<br>(Even when warned, my son shows no intention of / refuses to admit his fault.)
• Example: 彼は体調が悪そうなのに、どうしても病院へ行こうとしない。<br>Kare wa taichō ga warusō na noni, dōshitemo byōin e ikō to shinai.<br>(Even though he looks unwell, he simply refuses to / won't try to go to the hospital.)

Exam Trap: You cannot use 〜ようとしない for yourself in the present tense (*私は勉強しようとしない is ungrammatical), because you possess direct access to your own volition. It describes observed obstinacy in others.

3. Targeted Design vs. Natural Suitability: 〜向け vs. 〜向き

In JLPT vocabulary and grammar questions, the suffixes 〜向け (muke) and 〜向き (muki) attach directly to Nouns to describe applicability. However, they represent entirely different perspectives on intentionality.

┌────────────────────────────────────────────────────────────────────────┐
│                     〜向け  VS.  〜向き                                │

4. Opportunistic Secondary Action: 〜ついでに

Core Meaning & Nuance

〜ついでに (tsuide ni) translates as "while I'm at it...", "taking advantage of the occasion to...", or "conveniently doing Y along with main task X".

It describes a situation where the speaker is undertaking a primary, main errand or motion (Clause 1), and takes opportunistic advantage of that trip, momentum, or occasion to execute a minor, secondary task (Clause 2) that requires little extra effort.

Exemplary Sentences

• コンビニへお弁当を買いに行くついでに、郵便ポストに手紙を入れてきてくれない？<br>Konbini e obentō o kai ni iku tsuide ni, yūbin posuto ni tegami o irete kite kurenai?<br>(While you're on your way to the convenience store to buy lunch, could you drop this letter in the mailbox for me?)
• 図書館へ本を返却しに行ったついでに、駅前のスーパーで買い物を済ませた。<br>Toshokan e hon o henkyaku shi ni itta tsuide ni, ekimae no sūpā de kaimono o sumaseta.<br>(Taking advantage of the trip to return books to the library, I finished my grocery shopping at the supermarket in front of the station.)

Key Pragmatic Constraint

The action in Clause 1 is always the main, substantial objective. Clause 2 must be an incidental, subsidiary action. You cannot use 〜ついでに if both actions are equally massive or unrelated major events.
