promptest
Fastest to respond
Promptest is the superlative form of prompt—the most immediate or quickest to act.
Someone who is the promptest arrives or responds before everyone else: She was always the promptest to reply to emails.
The form is grammatically correct but rarely used; "most prompt" is more common in contemporary speech.
