At a glance: 5-letter words with R as 2nd and O as 4th
- All 54 matches follow the fixed pattern _R_O_.

Which words fit the R-and-O letter pattern?
The first letter is most often A: 11 entries begin there. B contributes 6, while C, D, P, and T each start 5 words. That makes ARROW, ARMOR, and ARBOR good pattern checks, but the A-heavy opening does not mean every answer begins with A.
Ten matches end in S and nine in N; seven end in R. PRIOR and ERROR show the R ending, while BROOK and CROOK end in K. Use a confirmed final letter to narrow the pattern before guessing from the first.
How to use 5-letter words with R as 2nd and O as 4th
For a word puzzle, treat _R_O_ as a filter, then apply any confirmed first or last letters. PRIOR, PROOF, and ERROR are familiar candidates to test against your clues; ARROZ and ERGOT are less common possibilities. The 16 Wordle-answer matches belong to this pattern, but the total list also includes words outside that answer set.
For Scrabble, ARROZ, TROOZ, and ORZOS lead at 14 points each, while BROOK and CROOK score 11. Those are tile scores before board bonuses. Dictionary choice matters too: the 54-word total does not mean every game accepts every entry, so check your game's word list when a disputed play hinges on one.
