All words share the '-ate' spelling, but their final stressed syllables differ. 'Predicate', 'complicate', and 'suffocate' end with the same /-keɪt/ sound as 'excavate', though with different stressed vowels. 'Locate' also ends in /-keɪt/ but has a different vowel in the stressed first syllable. 'Cultivate' ends in /-veɪt/, which is distinct from /-keɪt/.
