What does clash mean?
'Clash' denotes a forceful encounter between two things that cannot comfortably occupy the same space — whether bodies, armies, opinions, or calendar entries. Its earliest sense was acoustic: the ringing impact of metal on metal, such as swords against armour or cymbals in an orchestra. From that physical origin the word broadened metaphorically, so today a clash can be a street battle between demonstrators and police, a heated dispute between rival politicians, an incompatibility between bold colours or patterns in clothing, or simply two meetings scheduled at the same hour. The verb works the same way: two forces clash when they meet head-on and neither yields easily. Because the word implies friction rather than total destruction — a crash wrecks, but a clash is a contest — it carries a connotation of active opposition, sometimes violent, sometimes merely awkward. It is a compact, versatile term found everywhere from sports reporting and political analysis to fashion commentary and diary planning, which makes it one of the most useful conflict-words in English.
A loud collision or the sound of one; a violent confrontation between opposing people or forces; a serious conflict of interests, views, or schedules.
"The clash between the two boxers drew a record television audience."
Often used in plural form for extended confrontations: 'border clashes'.
To collide noisily or violently; to meet in open conflict or argument; (of colours, patterns, events, etc.) to fail to match or coincide well.
"Her red scarf clashed horribly with her orange coat."
Standard regular plural; commonly used for repeated or ongoing confrontations, as in 'weeks of clashes'.
"Several clashes broke out between rival supporters after the match."
The word 'clash' has been ringing in English since the sixteenth century — originally describing the sound of swords striking armour.

Etymology of clash
'Clash' first appears in English in the late sixteenth century, imitating the percussive sound of metal striking metal. It belongs to a family of imitative words formed by adding a vowel before a final consonant cluster — clack, clatter, clang, clank — all echoing hard impacts. There is no certain classical ancestor; the word appears to be native English onomatopoeia rather than a borrowing from Latin or French, though its exact early development is not fully documented.

'Clash' is common in both formal journalism and everyday speech. In British English it is frequently used for scheduling conflicts ('the fixtures clash'), while American speakers often say 'conflict' or 'overlap' in that context; the sense of armed or physical confrontation is universal.
