5 letter words with R as the second letter number 1,378 in all, and Wordle has already used 261 of them as answers.

5 Letter Words With R as the Second Letter such as ARBOR, ARDOR, and ARENA
5 Letter Words With R as the Second Letter, starting from ARBOR

5 letter words with R as the second letter have a vowel in the third position more than four times out of five. Wordle has already used CRAMP, CRANE and CRANK, three answers built on that shape.

Since R is fixed in the second position, the third tile is what separates one answer from another. Starting with a vowel there ends more of the puzzle than a consonant does.

126 are words most players would guess without hesitation. 20% end in S, the ending that repeats most among them. Updated August 2026
