6-letter words with R as the 4th letter and O as the 5th letter

The pattern is _ _ _ R O _: the fourth and fifth letters stay fixed, while the first three and final letter vary. Familiar matches include MIRROR, NARROW, TERROR, BORROW, and CARROT. Only 18 matches fall among the 25,000 most frequent English words, so expect a mix of everyday entries and specialist vocabulary.

At a glance: the R-O pattern

• There are 116 tournament-dictionary words matching the six-letter pattern.
• Collins includes 112 matches; NWL2023 includes 88, and ENABLE includes 77.
• MIRROR, HORROR, NARROW, and TERROR are among the recognizable examples.
• M leads the first-letter group with 15 words; P follows with 10.

Which endings dominate this R-O pattern?

S is the leading final letter: 31 words end in S. N comes next with 24, and W has 16, so these three endings account for 71 matches. That gives you a practical way to narrow a clue when the last tile is still uncertain.

The ending groups have recognizable examples. PATRONS and MACROS illustrate the S group, while NEURON and MATRON finish in N. NARROW, BORROW, and BARROW show how often W appears after the fixed R-O pair.

M starts 15 matches, more than any other first letter; P starts 10. B, C, and S each start seven. The opening letters are more spread out than the endings, so testing a final letter often narrows this pattern faster than guessing the first.

Which matching words score highest?

ZORROS tops the scoring list at 15 points, with CHYRON next at 14. IMPROV and HYDROS each score 13, while HARROW, FARROW, FURROW, and YARROW each reach 12. These are stronger tile totals than familiar choices such as MIRROR or BORROW.

The word pool changes by game dictionary: Collins has 112 entries, compared with 88 in NWL2023 and 77 in ENABLE. The 116 6-letter words with R as the 4th letter and O as the 5th letter are not all accepted everywhere, so check your game's word list before relying on a less familiar scorer.
