Words such as concentrate, arbitrate, frustrate, demonstrate, and illustrate share the spelling ending '-ate' and the unstressed pronunciation /eɪt/, similar to the final part of penetrate. However, they do not strictly rhyme with penetrate because the stressed vowels differ. A lookalike to note is 'penalty', which begins with the same 'pen' but is pronounced /ˈpɛnəlti/ and has a different ending.
