What does thread mean?
Thread is a familiar word with meanings that range from physical material to organized communication. Its basic sense is a long, fine strand of cotton, wool, silk, plastic, or another substance, as in sewing or weaving. A thread also means a narrow course through a subject or place, and in modern online discussion it refers to a chain of connected messages. The metaphor is natural because an actual thread links separate pieces into a continuous whole, just as a conversation can connect related ideas or replies. As a verb, thread describes passing material through a needle, weaving or interlacing it with other materials, and posting a response within an online discussion. In informal British and American English, the plural “threads” can mean articles of clothing, especially trousers. Thread is therefore both literal and metaphorical: it can describe something physically slender and strong, or an idea, exchange, or narrative that develops gradually while remaining connected.
A long, thin strand of material, especially one used in sewing or weaving; a connected sequence of ideas, messages, or events; or a narrow line or path through something.

Where does thread come from?
The word comes from Old English þrǣd, meaning a twist or strand of yarn, and ultimately from Proto-Germanic *thrēdu. Its Germanic relatives include Dutch draad, German Faden, Swedish tråd, and Icelandic þráður. Over time, the word developed figurative meanings for a connected course of thought, and later for chains of online messages.
