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

That fixed ending creates a compact pattern: every match finishes in RO, while the first three letters do the distinguishing. Nine words are common, but the rest range from familiar compounds such as MACRO and HYDRO to less everyday entries. Six matches are Wordle answers, so the pattern is worth checking when the final two tiles are settled.

At a glance: the R-O pattern

• There are 33 five-letter tournament-dictionary words with R fourth and O fifth.
• METRO, MICRO, INTRO, and RETRO are recognizable examples.
• Nine matches rank among the commonest English words.
• ZORRO leads the score list at 14 points; HYDRO follows at 12.
• All 33 are Wordle allowed guesses, and six are answers.

Which familiar words fit the pattern?

METRO, MICRO, INTRO, and RETRO are strong first checks because they use familiar letter combinations. MACRO and HYDRO extend the same ending into common word-building forms, while NITRO gives another recognizable route to the final RO.

The opening letters vary more than the ending: M is the most frequent first letter, with five matches, and A follows with four. That makes a known first tile especially useful; if your pattern starts with M, test MICRO, METRO, and MACRO before trying obscure options.

The 33-word total is the union of entries found in at least one tournament dictionary. ENABLE includes 18, Collins includes 30, and NWL2023 includes 24, so a word accepted in one game may not be accepted in another. Check your game's word list before playing an unfamiliar entry.

For a board-score target, ZORRO is the standout at 14 points, ahead of HYDRO at 12. FIBRO and CHIRO each score 10, while MICRO and MACRO score 9 apiece. The average score is 7.6, so the top two are clear exceptions rather than typical results.
