Synonym discussion

Sense: noun/1

Ice-breaker, conversation starter, and opener all refer to something used to begin social interaction, but they differ in tone and scope. Ice-breaker (most common in the social-games and team-building sense) suggests easing awkwardness or tension — the image is of 'breaking the ice' of silence. Conversation starter is more neutral and descriptive; it can be anything from a comment to a prop (e.g., a striking piece of jewellery), and it does not imply that the situation was awkward beforehand. Opener is the most informal and is especially common in pickup-artist and dating contexts (e.g., 'a cheesy opener'). In a classroom workshop, you would call the warm-up activity an ice-breaker, not an opener. At a party, 'Do you come here often?' is a classic (if clichéd) opener, whereas asking about the music playing is a natural conversation starter.

Etymology

The word is a compound of 'ice' (from Old English īs, meaning frozen water) and 'breaker' (from the verb 'break', Old English brecan, meaning to split or shatter). The term was first used in the 1800s for ships designed to break through ice-covered waters, and by the mid-1900s it had gained the figurative sense of something that eases social tension.
