The org-mode has Capture-Refile-Archive mechanism. I often use it to take notes and logs. I also want to use it to build my own vocabulary. For example, when I encounters some new words while reading some English text, I want to simply type C-c c v e to record the word into my vocabulary file Word-List-EN.org. I also want that words are categorized into Letters, e.g., cashew will be recorded into entry /C/CA. I want to type C-c c v E to record my Esperanto words into some file like vortaro.org. How to config org-capture-templates to implement this? I read the org-info and still have no clue. The manual says that I can use something like (function function-finding-location). But I have to define my own function-finding-location. Hope elisp masters can help me!
