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

The fixed pattern is ___RS_: positions four and five stay R-S, while the first three letters and final letter vary. Familiar options include COURSE, COARSE, SPARSE, and THIRST; less familiar entries account for most of the remaining matches. Only four are common by frequency, so the full set reaches well beyond everyday vocabulary.

The R-S slot pattern at a glance

• Exactly 23 matches place R and S in consecutive fourth and fifth positions.
• COURSE is a familiar fit, with the pattern in C-O-U-R-S-E.
• THIRST and COARSE show how much the opening letters can vary.
• Thirteen matches end in E; seven end in T.
• Only four entries count as common by the frequency measure.

Which 6-letter words have R fourth and S fifth?

The clearest everyday fits are COURSE, COARSE, SPARSE, THIRST, AVERSE, HEARSE, and HOARSE. Each locks R-S into the same two middle slots, but the letters around them change. COURSE and COARSE differ near the start, while THIRST ends in T rather than E.

The final letter quickly narrows the set. E closes 13 matches, T closes seven, and H, I, and Y appear once apiece. With E at the end, try COURSE, COARSE, AVERSE, HEARSE, or HOARSE before considering rarer forms such as BOURSE or AHORSE.

Starting letters offer another clue: S leads five matches and H leads four. A, T, and three other initials each begin multiple entries, while B starts just one. That spread means a known first letter can narrow the search, but it rarely identifies a single answer by itself.

When are these six-letter matches worth playing?

Use familiar words as anchors, not proof that every match is common. Dictionary coverage also differs: Collins includes 22, NWL2023 includes 12, and ENABLE includes 11. Some forms will not be accepted in every tournament list, so check your game's rules before committing.

For a score-first choice, THYRSE, THYRSI, HEARSY, and WAIRSH each score 12 points. Those spellings are less recognizable than THIRST, which scores 9, so raw face value is not the whole decision. A familiar word that fits your rack and board can beat an obscure high-value option.
