A device, object, or person that drips; something designed to release liquid in drops, such as a coffee dripper or an IV dripper.
From English 'drip' (imitative, possibly from Old English or Scandinavian) + '-er' (suffix meaning 'one who' or 'something that'), referring to something that drips.
The word 'dripper' beautifully shows how English's '-er' suffix is endlessly productive—you can add it to almost any verb to name a tool or person, which is why we have thousands of '-er' words.
