Someone who never gives up is persistent or tenacious. Someone who talks a lot is talkative, or garrulous if it gets tiring. Someone who thinks they are always right is self-righteous, dogmatic or, informally, a know-it-all. Many of these words carry a judgement, so check what each one adds before you use it.

For each description below, the first word is the safest choice. The later ones are more precise and more pointed.

Describe the behaviour when it matters

Words such as narcissistic, psychopathic or obsessive are clinical terms as well as everyday insults. In a review, a complaint or a hard conversation, describing what happened is usually fairer and harder to dismiss. “He interrupted me three times in the meeting” gives the other person something specific to respond to. “He’s so arrogant” gives them a label to dispute instead.
