5-Letter Words by Repeat-Letter Structure
This hub separates 5-letter words by how much information each word can return. No-repeat words test five independent letters, while repeated-letter words trade information gain for narrower, often later-game candidate fits.
Across the 12,478-word verified dataset, repetition is a major structural boundary for both Wordle strategy and general filter efficiency.
Repeat-letter routes
Repeated letters change how much new information each guess can return. This hub separates the no-repeat baseline from the repeated-letter subset and then routes you into the strongest next pages.
The broadest efficient opener pool and the base of most Wordle strategy.
Repeated-letter forms that matter once the board begins to constrain your options.
No-repeat words with exactly two vowels: the most practical balance of coverage and flexibility.
The smaller Tier 1 opener subset with three or more vowels and no repeats.
How repetition changes the dataset
The repeated-letter question is not binary only for gameplay. It also reveals how much structural diversity each word carries.
| Structure | Count | Share | Meaning |
|---|---|---|---|
| 5 unique letters | 8,013 | 64.2% | No repeated letters at all. |
| 4 unique letters | 4,024 | 32.2% | Exactly one repeated letter. |
| 3 unique letters | 433 | 3.5% | Heavier repetition and lower information yield. |

FAQ
Why is the no-repeat pool so important?
Because every position returns new information, the no-repeat pool is the strongest starting point for Wordle filtering and opener selection.
Are repeated letters bad in every case?
No. Repeated letters are weak as openers, but they become necessary later once confirmed tiles force you into a smaller candidate family.
Which page should I open next?
Use the no-repeat list for broad filtering, or the double-letter list when the board already points to repetition.
