The word lodge has several meanings:

1. A small house or cabin, often in the woods or mountains. People stay in lodges when they visit national parks or go skiing. A hunting lodge might be a cozy building where hunters gather, while a ski lodge offers hot chocolate and warmth after a cold day on the slopes. Many lodges are built from logs or wood and designed to blend into natural surroundings.
2. To become stuck or firmly positioned in something. An arrow might lodge in a tree trunk, or a popcorn kernel might lodge between your teeth. A splinter can lodge in your finger, making it painful until you remove it. The word suggests something has wedged itself in and won't come out easily.
3. To stay somewhere temporarily as a guest. When travelers lodge at an inn, they're renting a room for the night. Students might lodge with a host family during a trip abroad. This usage is somewhat old-fashioned; people today usually say “stay” instead of “lodge.”
4. A local chapter of an organization like the Elks or Masons. Members gather at their lodge building for meetings and social events.
