このデッキについて
Medical terminology becomes manageable the moment you learn how the words are built. This 300-card foundation combines high-yield prefixes, suffixes and combining forms with the common directional, diagnostic, procedural and body-system terms built out of them. Each card explains the term in plain English and, where it helps, breaks it into components — so the pattern transfers to a term you have never seen instead of stopping at the ones you memorized. Import it and the whole deck joins your spaced-repetition schedule. Terms you already know stretch out and drop out of sight; the ones that keep slipping come back until they stop slipping. What goes down is the number of terms you still don't know — not the time it takes to flip past 300 cards you mostly do.
よくある質問
- Does importing this deck use my AI allowance?
- No. Importing uses the saved deck as published; it does not run AI generation or use your AI allowance. The complete deck can therefore be imported on the free plan.
- What happens if I import the deck twice?
- Existing cards are skipped. A later import only adds genuinely new cards, so it does not create a second copy of the same material. Including re-imports after deletion, the same Memly curated deck can be imported up to three times per account over its lifetime.
- Can I change or remove cards after importing?
- Yes. Imported cards belong to your account. You can edit either side, delete cards, add notes, or move them to another deck.
- Can I study the same deck on web and mobile?
- Yes. The deck is added to your Memly account and stays available across the web app and the iOS and Android apps.
- Can I drill just prefixes, or just suffixes?
- Yes. Every card is tagged by element type — combining form, prefix, suffix, root, inflection and whole term — so you can filter to one type and work through it. Combining forms are the largest block at 115 cards, then suffixes at 74 and prefixes at 64.
- Does the deck teach word-building rules as well as definitions?
- Yes. Root, prefix, suffix and combining-form cards explain meaning and show how the element appears in an independently written clinical example.
- Where should I start if the whole list looks like noise?
- Start with the prefixes and suffixes. A few dozen of them recur across hundreds of terms, so they pay off across the rest of the deck faster than the whole-term cards do.
