woah

Woah is an interjection used to express surprise, astonishment, or sometimes dismay. It is a non-standard spelling of the word "whoa," which originates from the command used to stop or slow down a horse. Over time, "whoa" evolved into a more general exclamation of surprise applicable to situations beyond equestrian control.

The spelling "woah" is a phonetic variation that has become increasingly common in informal written communication, particularly in online contexts and text messaging. It reflects a pronunciation where the "o" sound is elongated. While "whoa" remains the more formally recognized spelling, "woah" is widely understood and used.

The use of "woah" is typically reserved for informal settings. In formal writing or speech, "whoa" or more conventional expressions of surprise such as "wow," "astonishing," or "unbelievable" would be more appropriate. The emotional weight carried by "woah" can range from mild surprise to significant shock, depending on the context and the speaker's tone. Its usage is primarily to convey an immediate, often spontaneous, reaction to something unexpected.
