Pronunciation & Spelling
Group by sound, not spelling: be and bee match the letter B (/biː/); see and sea are exact homophones of the letter C (/siː/); day and say share the /eɪ/ sound of the letter A. Pronounce abc as three separate letters /ˌeɪ biː ˈsiː/, not like a one-syllable word. Beware lookalike spellings starting with ab, such as abacus (/ˈæbəkəs/) and abandon (/əˈbændən/), which do not rhyme with abc.
