Upload my "Japanese-English Hiragana dictionary" for pocketbook. All words in it are written in hiragana. It has hiragana keyboard too. So you can type any Japanese word in hiragana and the dictionary will have found it. There is morphem search in the dictionary.
So if you type ののしった (cursed) the dictionary will show ののしる (to curse).
