The application accepts any inflectional form of a word, then presents a list of all matching inflections and lemmas, from which the definition may be accessed.
Size of Application: the apk is about 25MB, since it contains a compressed database holding the dictionary and morphological data. On first use, this database is unpacked and requires about 89MB of storage. Given this, it is recommended that you have at least 114MB of free space (though after database unpacking you will only use around 89MB of space).
