One-word substitution: English Language Notes for JLPT

One‑Word Substitution (JLPT – English Language)

Goal:
Replace a phrase or clause with a single word that keeps the meaning, grammar, and nuance of the sentence.

1. Simple Explanation

In English, many ideas can be expressed with a long phrase or clause.
A one‑word substitution is the skill of finding a single word that conveys the same idea.
It is often tested in the JLPT’s English‑language section (especially N2/N1) as a way to check vocabulary depth, nuance, and grammatical flexibility.

Examples

Original sentence	Phrase to replace	One‑word substitution	Resulting sentence
He left early because he had an appointment.	because he had an appointment	as	He left early as he had an appointment.
She was speaking loudly in order to be heard.	in order to be heard	to	She was speaking loudly to be heard.
Although it was raining, we went outside.	Although	though	Though it was raining, we went outside.

2. Key Points

#	Concept	Why it matters	Tips
1	Identify the phrase type	Helps you know the right substitution list	Pay attention to adverbial clauses, prepositional phrases, infinitive clauses, conjunctions, etc.
2	Match grammatical function	The substitute must fit the same syntactic slot	If the phrase is a subordinating conjunction, the substitute must also be one.
3	Preserve nuance	Some words carry subtle shades (e.g., notwithstanding vs although)	Use dictionaries or collocation lists to check nuance differences.
4	Check for collocations	Some substitutes only work with certain verbs/adjectives	Example: to works with to be heard, to help, but not with to be considered.
5	Avoid redundancy	The substituted word should not make the sentence clunky	Example: in order to → to (shorter, smoother).
6	Use “conjunction + clause” → “shorter word + clause”	Many exam questions target this pattern	Practice with although → though, because → as, since → because, while → whereas, etc.
