The word "sapolan" is a tricky one to spell due to its unusual pronunciation. It is pronounced /səˈpoʊlən/ and consists of three syllables. The initial syllable is "sa" which is pronounced with a schwa sound. The second syllable is "po" which is pronounced with a short "o" sound. The final syllable is "lan" which is pronounced with a long "a" sound. The spelling of the word may cause confusion due to the unusual combination of letters, but with practice, it can be mastered.
