pronoun
they; those guys; those bastards
Casual plural pronoun based on 奴; often dismissive, contemptuous, or hostile. Use for people the speaker feels distance from or looks down on, not for respectful reference.
奴らはまた遅刻した。
Those guys were late again.
奴らに見つかる前に逃げよう
Let's get out before they find us.
Neutral or written-style 'they'; much less rude or dismissive than 奴ら.
Casual 'those people/guys'; also can be rude, but it is more deictic, pointing to people psychologically or physically away from the speaker.
Singular base word meaning 'guy,' 'fellow,' or sometimes 'thing'; 奴ら is the plural form with ら.
Formed from 奴（やつ）, a casual and often derogatory word for a person or thing, plus the plural suffix ら. The spelling 奴 is conventionally associated with this rough, dismissive nuance.
