The spelling of the word "Shawnah" can be explained using the International Phonetic Alphabet (IPA). The first sound in "Shawnah" is represented by the /ʃ/ symbol, which is the "sh" sound. The second sound is the vowel sound /ɔː/, which is represented by the "aw" sound. The third sound is the nasal consonant /n/, and the final sound is the vowel sound /ə/, which is commonly known as the "uh" sound. Therefore, the correct spelling of the word "Shawnah" is phonetically transcribed as /ʃɔːnə/.
The name "Shawnah" appears to be a variant spelling of the more common name "Shawna", which in turn is a feminine form of the name "Shawn". The name Shawn is derived from the Irish name Seán, which is a variation of the Hebrew name Yochanan meaning "Yahweh is gracious". It's important to note that as a variant spelling, the etymology and origins of the name Shawnah may not have a distinct meaning of its own.
