Hairiest → It is formed from "hair" (from Old English "haer", meaning the fine thread-like strands growing from the skin) and the suffix "-iest" (meaning most). The word "hairiest" describes something that has the most hair or is covered in hair to the greatest extent.
Think of 'hair' as the fine strands growing from the skin, and '-iest' means the most. So, 'hairiest' refers to something that has the most hair.
