Will, bill, fill, hill, kill, and pill all rhyme with swill (/swɪl/), because their stressed vowel and final consonant match the /ɪl/ ending. Be careful with sight lookalikes that start with sw- such as swim (/swɪm/), swing (/swɪŋ/), and swish (/swɪʃ/): they have different endings and do not rhyme with swill.
