outhouse
Synonym discussion
Sense: noun/2
For noun/2, outhouse usually means a toilet in a small building outside the main house. Privy is close in meaning, but it sounds older and is often used when talking about the past. Latrine is more common for camps, military sites, or emergency settings, especially when several people share the same basic toilet area. Toilet is the broad everyday word and does not tell you where the toilet is. Restroom is common in public places and sounds much more modern and polite. If a cabin in the woods has a separate toilet building, outhouse is the clearest choice. If a shopping mall has modern facilities inside, restroom or toilet is the natural word.

Etymology
This word was formed in English from out and house. It first meant a small building standing outside the main house, and that older idea later gave rise to the more specific meaning of a toilet kept in such a building.
