The spelling of the word "kotexes" is a bit tricky, as it does not follow the standard rules of pluralization in English. The word refers to a brand of feminine hygiene products, and the plural form is created by adding "-es" at the end. In IPA phonetic transcription, it would be transcribed as /ˈkoʊtɛksɪz/, with stress on the first syllable "ko" and a final "s" sound that changes the "x" sound into a "ks" blend.
The word "Kotexes" is formed by adding the plural suffix "-es" to the brand name "Kotex". The term "Kotex" itself has an interesting etymology. It was initially introduced by Kimberly-Clark Corporation, an American company, in 1920 as a brand name for their new disposable menstrual pads. The origin of "Kotex" is a contraction of the words "cotton" and "texture". The company combined these two words to create a unique brand name that reflected the product's main material (cotton) and its texture. Over time, "Kotex" became a popularized term for feminine hygiene products, and the plural form "Kotexes" emerged as a way to refer to multiple pads or products from the Kotex brand.
