How to Use Obsidian to Organize and Retain English Vocabulary

Most people cram vocabulary into a notebook or a random flashcard app and never look at it again. A week later, the word feels familiar, but you can't recall it in conversation.

That’s not a memory problem. That’s a system problem.

I’ve been using Obsidian for English vocabulary for the past year, and it completely changed how I learn new words. Instead of a flat list, I get a living web of connections that naturally makes me remember things. Here’s how to set it up.

Why Not Just Use Anki or a Notebook?

Anki is great for pure spaced repetition. A notebook is fine for jotting down a word once. But neither helps you connect your vocabulary. When you meet a new word, part of learning it is seeing how it relates to words you already know.

Obsidian’s core idea is linked thinking. You create notes, and those notes can link to each other. Over time, those links become a map of your personal vocabulary.

For example, I have a page for "disconcerting" that links to my existing notes on "uneasy" and "dismissive" — words I learned weeks ago. That web of connection is what makes the new word stick.

Step 1: Choose a Simple Template

Don't over-engineer this. You don’t need a dozen fields. Keep the note lean so you actually use it. Here’s the template I recommend:

Fields per vocabulary note:

• Word: the target word
• Definition: short, in your own words (not copied from a dictionary)
• Example sentence: one natural sentence you wrote
• Related words: links to other notes (e.g., synonyms, antonyms, or words with a similar theme)

You can add a field for pronunciation if you like, but the three above are enough to build a strong mental model.

Step 2: Link, Don’t Just List

This is the golden rule. Every time you add a new word, ask yourself: Which word that I already know is similar or opposite to this one?

Let me show you with a real example. I recently added "serendipity". Instead of just saving it, I linked it to my existing note on "coincidence" and added a note: "fortunate coincidence — more positive." I also tagged it under #positive-vocab.

Now, when I review "coincidence," I see a link to "serendipity." The context overlaps. That makes both words easier to recall.

Tip: If you have no related words yet, let the note stand alone for a few days. As you add more vocabulary, you’ll naturally find points to connect them back. Don’t force it.

Step 3: Use the Graph View for Weekly Reviews

Obsidian has a built-in graph view. It shows every note as a node and links as lines. At first, your graph will look sparse. After a month, it turns into a constellation.

I do a quick weekly review: open the graph, zoom around, and click any word I feel fuzzy about. If a note has no links yet (i.e., it’s isolated), I make a conscious effort to connect it to something. This step alone adds 10 minutes to my week, but the retention payoff is huge.

Step 4: Use Spaced Repetition Without a Plugin (Optional)

You don’t need to install a heavy plugin. Just add a simple "next review" date field in your note. Every few days, hash through your notes in Obsidian's native query (Dataview) or simply scroll through the file tree. If a word feels automatic, push the review date out by two weeks. If you trip over it, review it again tomorrow.

This lightweight version will work better than zero review — and it doesn’t break your note-taking flow.

The Three Core Actions

Here’s what the whole process boils down to:

Does This Replace an English Level Test?

No. Obsidian is an excellent learning tool. But to know where your English stands right now, you still need a reliable benchmark.

That’s why I recommend putting your new vocabulary to the test. After using your Obsidian system for a few weeks, check in with a proper English Level Test. See if your reading and listening comprehension has improved. If it has, your system is working. If not, adjust your template — maybe add more examples or deeper definitions.
