Well, it depends on the use of the word. But here are some words
that might get you started. (I the same problem when writing my
term paper in English.)
accusation, animadversion, arraignment, attack, attribution,
castigation, censure, charge, chiding, complaint, criticism,
denunciation, depreciation, diatribe, disapprobation, disapproval,
disfavor, disparagement, expostulation, exprobation, impeachment,
implication, imputation, incrimination, inculpation, indictment,
invective, objurgation, obloquy, opposition, rebuke, recrimination,
remonstrance, reprehension, reprimand, reproach, reprobation,
reproof, repudiation, slur, tirade
These are some, but chances are one of these will work out for
you.
It took a while to think of how to get these words,mostly be
cause I am an epic failure in the subject, so !!
