Reading and lookups
The word popup
Clicking a word anywhere on Lingaku, in the app or on a page with the extension opens the same popup. It shows what the word means and records that you looked it up.

- Browser extension
Opening and closing it
Click a word to open its popup. On a narrow screen it opens full-screen. Ctrl+click or Shift+click opens the word’s dictionary page instead. Esc closes the popup.

Definitions
The popup shows the dictionary entries for the word, in the order set under Study options → Dictionary (see English meanings and monolingual definitions). A conjugated word shows its dictionary form and the forms between them.
Below the words come the kanji in it and names written the same way. Details, or Open dictionary entry in the app, opens the full page.
Your level and suspending
Signed in, the popup has the five level buttons N, S, F, K and M (New, Seen, Familiar, Known, Mastered). A marked button is the level Lingaku suggests. Choosing one sets your level for the word everywhere. See Levels and progress.
The pause button suspends the word: it stays at its level but is left out of reviews. Press it again to unsuspend. A word that needs attention has a flag button; clicking it dismisses the flag.
The bottom bar also shows how many times you opened the word and links to its lookup history.
What a lookup records
Each time you open a popup while signed in, Lingaku saves the lookup with the page and the sentence it came from. Words you look up often come first in your reviews. The first lookup also marks a New word Seen. Your lookups are listed on the Lookups page.
Adding a word to a deck
Each entry in the popup has an add button. It adds the word to your main deck as a card with its reading, its first meaning and the sentence you found it in. The menu next to it adds it to any other deck of yours, or sets which deck is the main one.
