Looks like an excellent rule! I’m curious to see if it works.
“Esta frase poderia soar melhor com o verbo antes de ‘\ 1’.” (Which, as always, please transform this into nice-sounding Portuguese if I’ve messed up “Talvez esta frase soasse melhor…”?)
and maybe COLOCACAO_ADVERBIO? This would be the beginning of a bi rulegroup with different contexts of misplaced adverbs.
