Definition: Somniloquacious is a term used in linguistics and philosophy to describe someone who speaks with a very short or precise vocabulary, often using words that are not commonly found in everyday conversation. This can lead to awkward and unnatural speech patterns, as well as difficulty understanding complex sentences. In other words, someone who uses a very limited or specific vocabulary is often seen as "somniloquical," which means they have a unique way of speaking that is not easily understood by others.
