Definition & Meaning of "not see hide nor hair of somebody or something "

What is the origin of the idiom "not see hide nor hair of someone or something" and when to use it?

The idiom "not see hide nor hair of someone or something" is believed to have its origins in the 19th century and has its roots in the literal idea that when tracking an animal or a person, the absence of both "hide" (the animal's skin) and "hair" (the fur or hair on the animal's body) would indicate that the subject being pursued has not been seen or encountered. Over time, this expression evolved into a figurative idiom, signifying the complete absence or total disappearance of someone or something, often with the implication of concern or mystery regarding their location.
