The correct spelling of the phrase "go tangent" is /ɡəʊ ˈtændʒənt/. The word "go" is spelled with a silent "e" at the end, while "tangent" is spelled with a "g" that is pronounced like a "j". The phonetic transcription shows how the word should be pronounced, with the stress on the second syllable of "tangent." The phrase "go tangent" is often used to describe a sudden change of topic in a conversation, or a person's tendency to veer off topic.
The phrase "go tangent" is actually a variation or an alteration of the phrase "go off on a tangent". The term "tangent" in this context refers to a mathematical concept, derived from Latin "tangens", meaning "touching".
In mathematics, a tangent is a line that touches a curve at a single point without crossing it. It represents a departure or deviation from a main line or path. Similarly, when someone "goes off on a tangent", it means they veer off from the main topic or subject of a conversation or discussion and start talking about something unrelated or unrelated to the main point.
Over time, the phrase "go off on a tangent" has been shortened to "go tangent", which is sometimes used colloquially to describe someone digressing or going off-topic during a conversation.
