Bothersome → It is formed from "bother" (originating from the late 19th century, possibly from the dialectal English 'bother', meaning to disturb or annoy) and the suffix "-some" (meaning characterized by or causing). The word "bothersome" means causing annoyance or disturbance.
Think of something that 'causes disturbance' or 'annoyance' — that's what bothersome means.
