The word "sea monster" is composed of two main parts: "sea" and "monster".
1. Sea: The word "sea" derives from the Old English word "sǣ", which has Germanic roots. It can be traced back to Middle Dutch "zee" and Old High German "meri" or "mere". Its ultimate origin is uncertain, but it may have connections to the Proto-Indo-European root "*mori" meaning "body of water". Over time, the word evolved and has been used to refer to large bodies of saltwater.
2. Monster: The term "monster" comes from the Latin word "monstrum", which referred to a supernatural manifestation or portent that was seen as a sign from the gods. It could represent both a good or evil omen, but gradually it started to be associated with strange, frightening, or abnormal creatures.
