RUST: The American Sign Language (ASL) sign for "rust"

What is the sign for "rust?"

The vast majority of adult native Deaf in the American Deaf Community just spell "R-U-S-T."

There simply is not a commonly accepted specific single sign for "rust" in widespread use in the Deaf community.

The closest would be to sign "red" + "powder" with perhaps a somewhat negative facial expression in the context of discussing metal.  The sign "powder" is done using a "rub-between-fingers" type of movement and is a multiple meaning sign that includes such meanings as: powder / soil / sand / grit / particulate / substance and other similar concepts.  The precise meaning of the (rub-between-fingers) sign is determined by context and sometimes (optional but not required) mouthing. 

See: for an example of the "powder" sign.

However, "RED-POWDER" still is not "the" sign for rust -- "red powder" is an abbreviated description of what (one type of) rust is like.

A description of a thing is not the same as a sign for that thing.

You can't just walk up to someone and sign RED-"rub-between-fingers" to mean rust. For the concept of rust to be understood by using just a couple of signs (instead of fingerspelling it) there must be enough context.

If you sign "RED-POWDER" to someone and there is dirt around they might think you are discussing (red) clay.  If there are cosmetics ("make-up") around, red powder might be interpreted as meaning "blush" (or blusher) -- a reddish cosmetic for coloring the cheeks.

To discuss rust out of context you should certainly spell it near the beginning of your conversation. If the person already knows what "rust" means there is no need to expand the concept or describe it further.

If you are discussing the type of rust that happens to metal and you spell "rust" to someone and they don't know what "rust" means and/or they have a "confused look" or ask you what rust is -- you can sign: YOU KNOW METAL? SUPPOSE WET LATER DRY TEND-to RED BROWN POWDER "on-surface"-[depiction]? THAT!

Of course there are more technical approaches to describing rust involving additional signs like O2 (for oxygen), PENETRATE-[4-handshapes-version], and deteriorate-[DISSOLVE / melt].

Yet still such approaches are only partial explanations of what "rust" is or what it is like -- and are not "signs" for rust.

Perhaps "if" someday one of the explanations for rust gets used over, and over, and over again while being truncated (shortened), lexicalized (becomes word or sign-like), and squished down into just a couple of movements -- yay -- we will have an actual sign. But -- that hasn't happened yet.

Also, for what it is worth, the curse of knowledge (for those of us who know the sign for oxygen is O2 and/or already know what rust is) -- we sometimes think that by signing O2 and other technical signs that we have successfully "communicated" -- when really the viewer may be no closer to understanding rust than if we had waved our hands in the air signing gibberish.  Explaining something using technical terms doesn't necessarily lead to understanding by our audience.

Worse, in our expansions we may give wrong information or carelessly leave out important information such as the fact that the rusting of metal typically requires water (or at least moisture) and oxygen (not just oxygen alone). Thus we might cause someone to think that metal will rust if exposed to dry "air." 

In our "explanation" we may without thinking -- totally overlook the fact that rust isn't only about metal.   "Leaves" of plants sometimes rust -- not due to oxygen but due to a "fungal parasite" (Source: Almanac (dot) com).

Rust is also the name of a color.  Launching into an explanation of "the decomposing of metal" might cause someone alarm when they are simply trying to buy "rust" colored curtains.

Again, context is important.  So is actually knowing what one is talking about in any particular situation.


1.  Oh and let's not forget "rusty!! Now there's an English concept that's a bugger to sign: "rusty" as in "knowledge or a skill impaired by lack of recent practice." (Source, Oxford).  (Perhaps:  I SINCE not-PRACTICE. NOW I AWKWARD.)

2.  John F. commented, "Recalling other conversations I have seen the red powder approach. Context is important. Rust can also afflict the aluminum rails of the backyard train my friend was describing as we were trying to get the locomotive to run!"
