In the Android dictionary, there are hundreds of abbreviations and all-caps combinations that are hardly ever used. However, when typing, these words keep popping up instead of the intended words.
The system in question is a non-rooted Android 7, and the keyboard is
Multiling O Keyboard.
Since apps cannot write to the built-in dictionary, I assume that Multiling stores user dictionary entries (like the addition or removal of words) in a separate file, and compares this file to the built-in dictionary.
Where does Multiling keep its word lists (for each language)?
Is there a way to remove all of these abbreviations and all-caps words, e. g. by batch-processing a list or by replacing a database file?
