The second word, "sox," is spelled phonetically as /sɑks/, with the 'o' representing a short vowel sound and the 'x' representing the 'ks' sound. When combined, "long sox" refers to a type of sock that extends up to or beyond the knee.
The term "long sox" is a colloquial variant of "long socks".
The etymology of the word "sock" can be traced back to the Old English word "socc", which referred to a light shoe or slipper. This word was derived from the Latin word "soccus", which had a similar meaning. Over time, the term "sock" specifically came to refer to a covering for the foot and lower leg.
The word "long" simply denotes something that has an extended length. When combined, "long socks" or "long sox" refers to socks that are taller or longer in length, typically reaching above the knee or mid-thigh.
