TRUE RHYMES: developed, undeveloped, enveloped all end in /ˈvɛləpt/ and rhyme with underdeveloped. LOOKALIKES: galloped (/ˈɡæləpt/), eloped and sloped (/loʊpt/) end in -loped but have different stressed vowels, so they do not rhyme. Note that undeveloped (un- + developed) differs from underdeveloped (under- + developed) only in the prefix.
