Questions tagged [polarity-items]
極性項目. Words that appear exclusively in affirmative or negative (or interrogative) environments. For example, the adverbial particle しか only appears in negative contexts. Some words have an association with one polarity but also appear outside that context; for example, 全然 appears chiefly in negative contexts but also appears in affirmative contexts. Some words, such as あまり, are polarity items only in certain uses.
