The word "yellow streak" is a figurative expression that originated in the early twentieth century. Its etymology can be traced back to two main components:
1. Yellow: The use of "yellow" to describe a cowardly or weak-willed person can be attributed to the historical association of the color yellow with fear or weakness. This association can be traced back to ancient times, where some cultures believed that yellow was the color of fear, sickness, or even betrayal. Over time, this association became embedded in various languages and idiomatic expressions, including English.
2. Streak: In this context, "streak" refers to a line, mark, or trace left behind by someone's actions, character, or behavior. The use of "streak" in idiomatic expressions can be seen in phrases such as "winning streak" or "mean streak", which metaphorically represent a pattern or tendency.
