Usage

What does -stress mean? The form -stress is a suffix that marks a feminine agent noun, which indicates a person who does an action. This suffix is occasionally used in a variety of informal terms, but it has lost popularity in recent years. Increasingly, -stress is seen as an unnecessarily gendered suffix for forming agent nouns because it identifies the "doer" as female. The suffix -stress is a combination of two similar suffixes: Old English -estre, which marked female agent nouns, and Old French -esse (see -ess), a common feminine ending for nouns. What are variants of -stress?When agent nouns ending in -stress are used to refer to a masculine- or neutral-gendered element, -stress becomes -ster, as in seamster (a male seamstress).

Etymology

Origin of stress¹

First recorded in 1275–1325; (noun) Middle English stresse, aphetic variant of distresse; (verb) derivative of the noun; distress

Origin of -stress²

-st(e)r + -ess

Explanation

The word stress is about pressure, whether it's pressure on a syllable of a word (TRAIN-er versus train-EE), an object (the bridge is designed to handle the stress of the cars), or a person (I am under a lot of stress). It says something about our culture, how much we love to use the word stress and keep redefining it to mean new things. The word first appeared in about 1300, when it meant hardship or a force to which someone is subjected. In the 1890s, we stretched the meaning to include "emphasizing something" and, in the middle of the 20th century, started to associate it with psychological pressure.
