The word "antilencocidin" is a mouthful to pronounce and spell correctly. Its spelling can be deciphered using the International Phonetic Alphabet (IPA) transcription as /ˌæntiˌlɛnˈkɑːsɪdɪn/. The prefix "anti-" means against, "lenco-" refers to white blood cells, and "-cidin" means a killer or destroyer. Thus, "antilencocidin" can be defined as a substance that destroys or kills white blood cells. Its pronunciation can be tricky, but understanding its IPA transcription can help in correctly spelling and pronouncing this complex term.
