True rhymes: emotionless /ɪˈməʊʃənlɛs/ shares the stressed /məʊʃən/ with motionless, and motion /ˈməʊʃən/ matches the first syllable. Notion /ˈnəʊʃən/ rhymes with motion but not with motionless because it lacks the /lɛs/ ending. Lookalike warnings: passionless /ˈpæʃənlɛs/ and frictionless /ˈfrɪkʃənlɛs/ end in the same -tionless spelling and /ʃənlɛs/ sound, but their stress falls on the first syllable (/pæ/ and /frɪk/), so they do not rhyme with motionless. Locomotion /ˌləʊkəˈməʊʃən/ contains the same /məʊʃən/ chunk but is not an adjective ending in -less.
