Why “foretaster” is a great word
FORETASTER — [Noun] A person, typically a servant or official, who tastes food or drink before another, especially to detect poison. From the prefix fore- (meaning "before" or "in front") + taster (meaning "one who tastes"). Unlike a "taster," who samples for quality, or a "food critic," who appraises for public judgment, the foretaster is an instrument of mortal precaution. It is the deliberate sip from a king's goblet, the methodical chew before the feast, the small, fatal delay that makes the palate a sentinel. In this role, the sense of taste becomes a tactile reconnaissance on the border of trust and demise.
