Teaching English as a second language presents several challenges. Some challenges include students being confused by words with multiple meanings and difficulties with pronunciation for non-native speakers. Additionally, cultural differences can make teaching literature challenging if stories reference content unacceptable in some cultures. Other difficulties include students' exposure to slang words and variations in English like formal vs. informal language. Spelling can also be hard for some students due to issues with reading words, pronunciation, mismatches between spelling and sounds, and the multiple sounds associated with letters in English.
