Just (adverb) — very recently; exactly or precisely; only or merely; barely. I have just finished reading the chapter.
Just (adjective) — morally right, fair, and deserved. The judge delivered a just verdict.
What Does Just Mean?
Just comes from the Latin justus meaning righteous or lawful, via Old French juste. The adjective meaning of fair and morally right entered English in the 14th century. The adverb senses — exactly, only, very recently — developed through the 15th and 16th centuries as the word broadened in everyday use.
Today just is one of the most frequent words in spoken British English, appearing in the top 50 most common words overall. Its power lies in its versatility: a single word can express timing ("I have just arrived"), precision ("That is just right"), minimisation ("It is just a small error"), near-miss ("We just made it in time"), and moral judgement ("She received just treatment").
Because just carries so many meanings, context is everything. The position of just in a sentence — before a verb, before an adjective, or as a standalone adverb — signals which meaning is intended. ESL learners often under-use just in informal speech, where it functions as a natural softening device, or over-rely on it as a filler in formal writing where it weakens the message.

Usage Notes
Key Points for Learners
- British vs American English: In British English, just with the present perfect is standard — "I have just eaten." American English often uses the simple past — "I just ate." Both are correct; choose based on your audience and context.
- Position matters: Just usually sits immediately before the word or phrase it modifies: "I just need a minute" (before the verb), "it is just wonderful" (before an adjective), "just over fifty" (before a preposition).
- Softening requests: Adding just to requests makes them more polite and less direct: "Could you just check this for me?" sounds more natural in British English than "Could you check this for me?" in many spoken contexts.
- Formal writing: In academic or formal writing, avoid using just as a general filler. Replace vague uses with more precise language: instead of "This is just an example," write "This is one example."

Etymology
From Latin justus (upright, righteous, lawful), from jus (law, right). Entered Middle English via Old French juste in the 14th century with the adjective meaning of fair and morally correct. The adverb uses — "exactly" (15th century), "barely" and "only" (16th century), and "very recently" (17th century) — all developed from the core idea of something fitting precisely within the bounds of what is right or exact. Related words include justice, justify, adjust, and injustice.
