nay-sayer
Constant voice against
A nay-sayer is someone who habitually opposes, objects, or expresses doubt—especially when others are enthusiastic.
The term carries negative connotations, suggesting the person's skepticism is reflexive rather than reasoned: Every office has a nay-sayer who shoots down new ideas.
Also spelled naysayer.
