Originally, the term "spleen" referred to the biological organ responsible for the production of blood and the removal of old red blood cells. However, over time, it began to be associated with emotions such as ill-temper, melancholy, or irritability. The earliest recorded usage of "spleen" in this emotional sense is from the mid-16th century.
The suffix "-less", meaning without, free from, or lacking something, was added to "spleen" to form "spleenless".
