Loud, violent conflicts or disagreements, or the loud sound made when two hard objects hit together.
Clash is imitative in origin (onomatopoeia), created from the sound 'clash' itself. The word appeared in English around the 1500s and was used both for literal sounds and metaphorically for conflicts.
Clash is a perfect example of onomatopoeia—the word literally sounds like what it means, which is why it's been used for both sword fights and musical conflicts for 500 years!
