組成stop + -er, the ending that turns a verb into 'the thing or person that does it' — as in opener, cooker, teacher. So a stopper is simply 'the thing that stops'. The -er ending came into English through Old English -ere, and traces back through Germanic to a Latin ending -arius that was borrowed long ago.
