Downstair vs. Downstairs: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on November 7, 2023
"Downstair" is a rare, often incorrect variant of "downstairs," which refers to the area or floors located below the main level of a building.

Key Differences

"Downstair" is seldom used and generally considered a nonstandard form of "downstairs," which designates the lower floor or levels of a structure. The prefix "down-" implies a lower position or descent, and while "stair" refers to the steps themselves, "stairs" is the more common form when referring to the concept of levels in a building. "Downstair," when encountered, is usually a misspelling or a typographical error. In contrast, "downstairs" is the correct term to describe something located on the lower floors of a building and is commonly used in both spoken and written English.

"Downstair," lacking the final -s, diverges from the standard plural form used in compound nouns describing parts of a building. In English, such compound nouns are typically plural when they refer to a system or network within a structure, as in "stairs" or "hallways." "Downstairs," with the -s, aligns with this convention, indicating not just one stair, but the entire lower level or the stairway as a whole. Therefore, "downstair" may confuse readers or listeners, as it suggests a singular form where a plural is expected.

In usage, "downstair" is not recognized by most dictionaries and is likely to be corrected to "downstairs" by spellcheckers and editors. "Downstairs" is the standard adverb or adjective, used to describe an action taking place on a lower floor ("He went downstairs.") or to qualify a noun as being on a lower floor ("The downstairs bathroom is available."). The distinction is important for clear communication, as using the standard "downstairs" ensures understanding and correctness.

The rarity of "downstair" is such that it is not included in most grammar rules or style guides, which focus on "downstairs" to describe locations beneath the ground floor. "Downstairs" can also be used metaphorically, to indicate a lower status or degradation ("Moving from CEO to an entry-level position felt like going downstairs."), a usage that "downstair" does not share, due to its nonstandard and uncommon nature.

"Downstair" may sometimes appear in older texts or in dialectal usage, but it remains an anomaly. "Downstairs," on the other hand, is universally recognized and used to indicate direction ("Let's move the furniture downstairs."), location ("The party is happening downstairs."), or even as a noun ("The downstairs has been renovated recently."), demonstrating its versatility and established place in the English language.
