Biggest problem are “sinéreses” and “diéreses”. It seems some consonants like “n” and “m” in the next syllable can cause it.

['ãe',
'ão',
'õe',
'au',
'ou',
'iu(?!m$)',
'[áâàãéêíóôú][iu]',
'[aieou][iu](?=[aeo])',
"ai(?!m$|ns$|r$|ç[ãõ]|[nm]#{ONSET}|nh)",
"eu(?![nm]#{ONSET})",
"ei(?![nm]#{ONSET})",
"ui(?!m$|ns$|ç[ãõ]|r$|dade$|z|[nm]#{ONSET}|nar$|d[ao]$|dora?$)",
"oi(?!m$|ns$|ç[ãõ]|r$|dade$|z|[nm]#{ONSET}|nar$|dora?$)",
'[aáâàãeéêiíoóôuúy]']
NUCLEUS = 
"(?:#{NUCLEUS_RULES.join('|')})"

The concept of “rhyme” does not help in this algorithm. It seems the concept makes no sense for syllable separation in portuguese (by an algorithm, at least)

"#{ONSET}?#{NUCLEUS}"
