5-letter words with I and O
728 words are exactly five letters long and contain both I and O, in any order and any position. That is 4.9% of every five-letter word.
What you know
Two letters confirmed, no positions confirmed. This is the classic two-yellow-tile board.
For example: aboil, dhoti, igapo, molvi, osier, rosit.

Playing a two-letter clue
At 728 words this pair sits mid-table, ranked 53 of 323. That is usually small enough to scan and large enough that the answer is genuinely in here. 31% of them put the two letters next to each other, which is often enough that testing an adjacent placement first is a reasonable bet.
I and O are both vowels. Five-letter words with two different vowels are the norm rather than the exception, so confirming a vowel pair narrows less than it feels like it should. The real progress comes from the consonants you rule out alongside them.
The habit worth building is to stop hunting for the answer and start hunting for the guess that splits this list fastest. With 728 candidates in play, a word that tests three untried letters is nearly always better than a word that merely fits everything you already know. Once one of I or O turns green, drop this page and use the position lists instead: I in the middle, ending in O, or starting with I.
Quick answers
How many 5-letter words have both I and O?
728 of them, out of 14,858 five-letter words, which is about 4.9% of the length. At 728 words this pair sits mid-table, ranked 53 of 323. That is usually small enough to scan and large enough that the answer is genuinely in here.
Does the order of I and O matter here?
No. This list takes any five-letter word that contains both letters, wherever they fall, so I may come before or after O. 31% of them put the two letters next to each other, which is often enough that testing an adjacent placement first is a reasonable bet.
How do I use this list in Wordle?
Two yellow tiles is exactly this situation: both letters belong, neither is where you put it. Work down the list and pick a word that moves both letters to new slots while also testing letters you have not tried. Repeating a letter in a slot you already know is wrong wastes a whole guess.
Which letters do these words usually start with?
The most common opening letters here are O (103), P (57), M (50). I and O are both vowels. Five-letter words with two different vowels are the norm rather than the exception, so confirming a vowel pair narrows less than it feels like it should. The real progress comes from the consonants you rule out alongside them.
Can I narrow this further?
Yes. If you know where one of the letters sits, switch to 5-letter words starting with I, 5-letter words ending in O, or 5-letter words with I in the middle. A fixed position cuts far harder than a second loose letter.
Swap the second letter
Keep I, pair it with something else.
Swap the first letter
Keep O, pair it with something else.
