How to pronounce "Lion"?



Greetings to you, Zlata Mishkova!
The pronunciation of 'lion' is actually the same in both British English and American English. Using the International Phonetic Alphabet (IPA) you can pronounce this word as: /ˈlaɪ.ən/.
The first syllable sounds like the word 'lie' while the second syllable rhymes with '-on' in 'lemon', 'open', or 'cotton'. The trick would be saying the 2 syllables right after the other making it sound like: 'layən'.
