3.2 Verbs, Adjectives, Adverbs & Collocations

The 文脈規定 (Context) Task

The contextually-defined expression task (文脈規定, bunmyaku kitei) is 問題4 and the largest single vocabulary task at about seven items — the biggest driver of your vocabulary sub-score. Each item is a sentence with a blank, and the four candidate words are all real, all grammatically possible, and often related in meaning. You must pick the one the context demands. Success rests on a broad active vocabulary of N2 verbs, adjectives, and adverbs, plus the collocations — the word pairings native speakers expect.

High-frequency N2 verbs

N2 mixes native (和語) verbs with Sino-Japanese (漢語) する-verbs. Frequently tested:

• 把握する (haaku suru) — grasp / get a firm handle on (状況を把握する).
• 検討する (kentou suru) — examine / weigh before deciding (not merely 'discuss').
• 実施する (jisshi suru) — carry out / implement a plan or survey.
• 伴う (tomonau) — accompany / entail (危険を伴う, entails danger).
• 取り消す (torikesu) — cancel / retract (予約を取り消す).
• 見込む (mikomu) — expect / forecast (an increase).
• 見合わせる (miawaseru) — suspend pending review (運転を見合わせる).

Note the collocation locks: 状況を『把握』する, 予約を『取り消す』, 運転を『見合わせる』. The exam offers a near-synonym that violates the pairing — for example あきらめる (give up entirely) where 見合わせる (postpone but keep the option) is meant.

Transitive / intransitive pairs (自動詞・他動詞)

The rule: intransitive verbs take が and describe a change that 'just happens'; transitive verbs take を and require an agent. 文脈規定 exploits this — if the object in the blank's clause is marked with を, only the transitive member fits; if the thing changing is the が-subject, choose the intransitive. Compare 会議が始まる (the meeting begins on its own) with 会議を始める (someone begins the meeting).

Adjectives, adverbs, and mimetics

Common N2 な-adjectives include 曖昧 (aimai, vague), 地味 (jimi, plain), 派手 (hade, flashy), 慎重 (shinchou, cautious), 妥当 (datou, valid/appropriate), and 深刻 (shinkoku, serious). Useful い-adjectives include 厳しい (kibishii, strict/harsh), 険しい (kewashii, steep/grim), and 鋭い (surudoi, sharp).

Adverbs and mimetics (擬態語, gitaigo) are heavily tested because English lacks one-to-one equivalents:

Learn the collocation, not just the gloss: ぐっすり pairs with 眠る (sleep), うっかり with 忘れる／間違える (forget/err), and ばったり with 会う (meet). かえって marks an outcome opposite to expectation — 薬を飲んだらかえって悪化した ('I took the medicine but got worse instead').

Collocations and set phrases

文脈規定 rewards idiom awareness: 首を縦に振る (kubi o tate ni furu, nod = agree/consent), 失敗を糧にする (kate ni suru, make failure one's nourishment), 見る価値がある (miru kachi ga aru, be worth watching), 予想に反して (yosou ni hanshite, contrary to expectations), and 気に入る (ki ni iru, take a liking to). These are fixed units; swapping a synonym of one component word breaks the phrase and marks the wrong answer.

A worked 文脈規定 item

Prompt: 両親の体調を考えて、旅行を（　）ことにした。('Considering my parents' health, I decided to ___ the trip.') Options: あきらめる / 見合わせる / 取り消す / 断る. The context is a decision made out of concern — most naturally a temporary hold. 見合わせる ('put on hold pending review') fits best: the trip is postponed, not abandoned forever. あきらめる (give up entirely) is too final, 取り消す (cancel a booking) needs a concrete reservation as its object, and 断る (decline an offer) needs someone doing the offering. A context favoring a reversible pause selects 見合わせる — precisely the kind of fine distinction 問題4 is built to test.

Register and a second worked item

文脈規定 also tests register: a formal report sentence prefers 漢語 する-verbs (実施する, 検討する) and formal connectives (により), while a casual conversation prefers 和語 verbs (やる, 決める) and plain connectives (から). A word can be semantically fine yet stylistically wrong for the frame, and the exam counts that as incorrect.

Second worked item: 彼の説明は（　）で、結局何が言いたいのか分からなかった。('His explanation was ___, so in the end I couldn't tell what he wanted to say.') Options: 明確 / 慎重 / 曖昧 / 妥当. The result clause — 'couldn't tell what he meant' — demands a word meaning unclear, so 曖昧 (aimai, vague) is correct. 明確 (clear) contradicts the outcome, 慎重 (cautious) describes manner not clarity, and 妥当 (valid/reasonable) evaluates correctness, not comprehensibility. Reading the result clause first tells you the required polarity of the adjective before you even weigh the options.
