IPA: /ˈwiːˌkɛndər/
KK: /ˈwiːˌkɛndər/
A person who goes on a short trip or vacation during the weekend.
Many weekender trips are planned to nearby cities for a quick getaway.
Weekender → It is formed from "week" (from Old English *wice*, meaning a period of seven days) and "-er" (meaning a person who). A weekender is a person who spends the weekend away from home or engages in activities during the weekend.
Think of someone who enjoys activities during the 'week' — the '-er' just means a person. A weekender is someone who makes the most of their weekends.
