Light-Verb する Compounds in Japanese Technical Prose

Core examples: 研究する, 説明する, 対応する, 実施する, 検討する, 分析する, 申請する, 承認する.

The formal verb engine hiding in plain sight

Technical Japanese often feels verb-heavy and noun-heavy at the same time:

調査を実施する analyze data 対応を検討する 申請を承認する

A huge amount of formal Japanese is built from Sino-Japanese nouns plus する. These are often called する-compounds or verbal nouns.

The key principle:

する compounds turn abstract nouns into reusable formal actions.

They are central to government notices, business reports, academic writing, manuals, meeting minutes, and technical prose.

The basic pattern

A noun combines with する:

研究 + する → 研究する to research

分析 + する → 分析する to analyze

申請 + する → 申請する to apply

The noun carries the action concept. する supplies verbal grammar: tense, negation, passive, potential, causative, politeness.

分析しました analyzed

申請されました was applied/submitted

承認できません cannot approve

Why formal prose loves する compounds

する compounds are useful because they are modular. Institutions need reusable action nouns: implementation, response, review, approval, application, confirmation, investigation.

Examples:

実施する carry out / implement

対応する respond / handle / address

検討する consider / examine

承認する approve

These words sound formal, process-oriented, and bureaucratically neutral. They let documents describe actions without sounding personal.

Translation is domain-sensitive

A common mistake is translating する compounds with one fixed English verb.

対応する

Possible translations:

• respond,
• handle,
• address,
• deal with,
• support,
• take action,
• accommodate.

The right English depends on domain.

お客様に対応する serve/respond to customers

問題に対応する address a problem

新制度に対応する adapt/respond to a new system

Do not choose English too early.

Transitivity and particles

Some する compounds take を:

データを分析する analyze data

申請書を提出する submit an application form

Some pair with に:

問題に対応する respond to a problem

変化に対応する adapt to change

Some can appear as noun + を + する:

説明をする give an explanation

or as a compound verb:

説明する explain

The particle frame is part of the word.

Passive and institutional style

する compounds easily become passive:

実施される be carried out

承認された was approved

検討されている is under consideration

This is why they are common in news and official writing. The actor can be backgrounded.

新制度の導入が検討されています。 The introduction of a new system is being considered.

This sounds institutional and cautious.

Example walkthroughs

研究する

To research. Academic and general formal use.

Learner action: learn both 研究する and 研究 as noun.

説明する

To explain. Can also be 説明をする.

Learner action: watch object marking: 内容を説明する.

対応する

Respond/handle/address.

Learner action: translate by domain, not by a fixed gloss.

実施する

Carry out/implement.

Learner action: expect in surveys, programs, policies, tests.

検討する

Consider/examine.

Learner action: do not treat as decision; it often means pre-decision review.

分析する

Analyze.

Learner action: common in academic and technical prose.

申請する

Apply/submit application.

Learner action: know related nouns: 申請書, 申請者.

承認する

Approve.

Learner action: common in workflow, legal, school, and office contexts.

する-compound routine

1. Identify the noun core.
2. Decide whether it names action, process, result, document, or status.
3. Check particle frame: を, に, が, と.
4. Check voice: active, passive, potential.
5. Determine domain: academic, government, business, technical.
6. Choose a natural English verb only after context.

The noun core controls the verb frame

A する compound is not just “noun + do.” The noun core tells you what kind of institutional action is being performed.

申請する to apply

This often takes に or を depending on structure:

ビザを申請する。 apply for a visa.

市役所に申請する。 apply to city hall.

対応する to respond/address/deal with

This often points to the problem or counterpart:

問題に対応する。 address the problem.

お客様に対応する。 deal with/respond to customers.

The English verb changes by domain. The Japanese action noun remains stable.

Formal prose prefers reusable action nouns

Technical and bureaucratic Japanese likes する compounds because they are reusable and easy to nominalize:

実施する → 実施 検討する → 検討 分析する → 分析 承認する → 承認

This supports sentences like:

調査を実施し、結果を分析したうえで、対応を検討する。 We will conduct a survey, analyze the results, and consider a response.

The prose sounds process-oriented because the key actions are nouns.

Passive and nominal extensions

する compounds easily enter passive and nominal structures:

承認される be approved

実施された調査 the survey that was conducted

検討中 under consideration

対応済み already handled

This is why they dominate manuals, research abstracts, meeting minutes, and notices.

Translation strategy

Do not choose the English verb too early. First identify the noun core:

• 分析: analysis
• 検討: consideration/examination
• 実施: implementation/conducting
• 対応: response/handling
• 承認: approval

Then ask what the domain wants:

対応する answer a message, handle a complaint, respond to a disaster, support a device, address a policy issue.

The Japanese word is broad because institutions like broad action nouns. English often requires a narrower verb.

Suggested functions:

1. Noun core highlighter: 検討, 実施, 対応.
2. Particle frame display: Xを分析する, Xに対応する.
3. Voice toggle: active/passive/potential.
4. Domain translation menu: business, legal, academic, public notice.
5. Plain Japanese paraphrase.

Final rule

する compounds are the engine of formal Japanese action.

Learn the noun core, the particle frame, and the domain. Do not translate mechanically. In technical prose, する is light, but the compound is heavy with institutional meaning.
