Only spelling-pattern similarity: all end with '-fully'. However, the stressed vowel and following sounds differ from 'successfully' (IPA səkˈsesfjli). These words have stress on the first syllable and the '-fully' part is unstressed with /fə.li/ or /fəli/, while 'successfully' has /fjli/ after the stressed syllable.
