Making a loud, rattling noise, like hard objects repeatedly hitting each other.
From Middle English 'clateren,' possibly imitative of the sound itself. The '-ing' suffix makes it a present participle or gerund form of the verb 'clatter.'
Onomatopoeia is when a word sounds like what it means—'clattering' is perfect because saying it out loud mimics the actual sound of dishes or pots banging together!
