IPA: /ʌnˈdʒʌst/
KK: /ʌnˈdʒʌst/
Not fair or just; violating principles of fairness or justice.
The decision to fire her without warning was unjust and left many employees feeling unhappy.
Unjust → It is formed from "un-" (meaning not) and "just" (from Latin "justus", meaning lawful or fair). The word "unjust" means not lawful or not fair.
Think of 'not' ('un-') being added to 'fair' ('just') — that's why unjust means something that is not fair.
