These -idly adverbs share the same written suffix and the unstressed ending /ɪdli/ with splendidly, and they have the same first-syllable stress pattern; but their stressed vowels differ (e.g. /æ/, /ɒ/, /ɪ/), so none of them fully rhymes with /ˈsplɛndɪdli/. Splendid is the base adjective and has the same initial spelling splen- but lacks the -ly suffix.
