5-letter words with I as the 3rd letter and O as the 5th letter

Every entry ends in O and holds I in the third slot, so the frame is __I_O. Two opening letters do most of the work: A starts 5 words and C starts 5, giving the list an unmistakable borrowed flavour, with AMINO, AMIGO, AMIDO and AVISO on one side and CHICO, CHINO, CHIAO and CHIMO on the other. Only three count as common English, and just two are Wordle answers.

The __I_O list at a glance

• 23 five-letter words put I third and O fifth.
• A and C each open 5 words; Q, I, S and T open 2 each.
• QUIPO scores 16, with AZIDO next on 15 and QUINO on 14.
• Seventeen have a dictionary definition and only 3 are common.
• PRIMO and RHINO are the only Wordle answers.

Why A- and C- openings dominate

Ten of the 23 words begin with A or C, and both clusters lean on borrowed vocabulary. AMINO, AMIGO, AMIDO, AVISO and AZIDO take the A slot, while CHICO, CHINO, CHIAO, CHIRO and CHIMO fill the C slot. Five of the ten start CHI-, so the openings repeat narrowly.

The rest of the list mixes Latin and Japanese loanwords, from EJIDO and TRIGO to MAIKO and TAIKO. Practically none of it appears in everyday writing, which is why only three entries meet the common-word cutoff.

Which __I_O words are worth playing?

QUIPO leads on 16 points and AZIDO follows at 15, with QUINO on 14 and EJIDO on 13. Q holds the top of that table, while a J or Z does the work just below, so premium tiles decide the ranking in a group this small.

Collins carries 21 of the 23 entries, NWL2023 only 17 and ENABLE 16, so most borrowed spellings are at risk in a stricter game. Confirm your game's word list before you commit a Q or a J to one of them.
