5 Letter Words Ending in ION That Work in Wordle
Only three of the 11 words ending in ION are accepted as Wordle answers. That is one of the smallest pools for any three letter ending filter, which is both a challenge and an advantage. Once you confirm the ION pattern, you are choosing between just three words.
Onion is the most recognizable of the three and a strong first guess if you already have the ending locked. It tests two common consonants and a doubled vowel, which gives useful feedback either way.
Union shares four of its five letters with onion, swapping only the first letter. If your board rules out the O in position one, union is the next logical move.
Scion is the trickiest of the three for most players. The SC opening is unusual, and the word itself is not part of everyday conversation for many people. If onion and union are both eliminated, scion is your answer.
