Etymology
The word "indoor" is quite straightforward, as it's essentially a compacted version of an older phrase, making its meaning very clear from its parts.
The Etymology of "Indoor"
The word "indoor" comes from a simple shortening of the phrase "within door" or "within doors."
"Within" means inside or on the inner side of.
"Door" refers to the entrance or threshold of a building.
So, the original, longer phrase literally meant something that is "inside the house or building, past the door."
First Known Use and Meaning
The word "indoor" as we use it today (as an adjective) emerged in the English language relatively late, around the late 17th or early 18th century (sources suggest the 1670s or early 1700s).
Its first and main meaning was the same as it is now: "located, used, or happening inside a house or building." It was created to act as a direct opposite to the older word "outdoor" or the phrase "without door."
In short, English speakers decided that saying "indoor pool" was much faster and more convenient than saying "within-door pool," and the shortened word stuck!
