The term security blanket has been in use since the 1940s, and the origin of this phrase may be surprising. We will examine the definition of the term security blanket, where it came from and some examples of its use in sentences.
A security blanket is a small piece of fabric that a child uses for comfort. Probably the most famous depiction of the use of a security blanket is in the comic strip Peanuts, drawn by Charles Schulz. In the strip, a character known as Linus is never seen without his security blanket. The term security blanket is also used figuratively to mean a source of support or comfort. Interestingly, the term security blanket was originally used as an American military term in the 1940s, to mean the measures taken to keep military plans out of the hands of the enemy and to preserve secrecy. By the 1950s the term security blanket was applied to an actual comfort item for children, and soon after in the 1960s, it also took on a figurative meaning.
