How it's used

This idiom carries a heavy, serious tone and is typically used to describe someone who is perceived as dangerous or manipulative. It is far more formal than everyday descriptions of someone being sneaky or mean. Because it implies a deep, calculated malice, it is rarely used in casual banter and is more common in serious warnings or dramatic storytelling.

Examples

He is always smiling at you, but he actually has ulterior motives.

Common phrases

obviously having ulterior motives
to guard against those with ulterior motives

Common mistake

Learners often use this to describe someone who is simply lying or being annoying, but it is too strong for those situations. It should be reserved for people who are actively plotting harm or have a hidden, sinister agenda.
