posture · pasture · pasteurization
Similar spelling, similar sound — three completely unrelated words. One vowel swap separates posture from pasture; pasteurization is a much longer word hiding behind the same start.
posture and pasture differ by a single vowel — /ɑː/ vs /æ/ — but mean completely different things. pasteurization shares the same opening sound as pasture, but it's a much longer, unrelated word — named after the scientist Louis Pasteur, not the fields where animals graze.
the way you hold your body — 'sit up straight, fix your posture' — nothing to do with farms

Key difference
posture /ˈpɑːs.tʃər/: how your body is held — back, open vowel, like “pot”. pasture /ˈpæs.tʃər/: grazing land — flat, front vowel, like “cat”. pasteurization /ˌpæs.tʃər.aɪˈzeɪ.ʃən/: the same opening sound as pasture, but five syllables long, with the main stress on “-ZAY-”. It's named after Louis Pasteur — the resemblance to pasture is a coincidence, not a real word-family connection.
