provocative language - insults benvolio with adjective 'coward' - established as quick to anger (his folly) as it took less than two lines to offer a fight upon his entrance
to scorn at our solemnity this night
combination of sibilance and plosive - language dripping with harsh sounds but also ominoushissing undertone

directaddress 'thou' shows he doesn't shy away from confrontation and is direct and almost violent in the way he expresses himself
wretched boy
exit is coloured with violence - shows no regret which is his hamartia and what leads to his death - shown to be folly of youth, not just because he is quick to anger but also Romeo, mercutio and benvolio is - the folly of the male youth
