The spelling of the word "NAWAS" can be explained using the International Phonetic Alphabet (IPA). The first sound is "n" (/n/), which is followed by a short "a" sound (/æ/). The next sound is a voiced "w" (/w/) which blends into the following short "a" sound. The final sound is an unvoiced "s" (/s/). So the whole word is pronounced as /næwæs/. It is important to spell words correctly to avoid confusion and convey clear communication.
