5-letter words with O as the 1st letter and S as the 5th letter

An O at the front and S at the end leaves a compact set, from familiar choices like OPENS and OASIS to less common entries such as ORZOS. The dictionary counts overlap, so the combined total is 74, not the sum of each source. That distinction matters when you are checking a game’s word list.

What stands out in this O-to-S pattern?

• The O-first, S-last pattern has 74 five-letter matches across the listed tournament dictionaries.
• OPENS, OASIS, OVERS, and OVENS are among the recognizable examples.
• Only four entries meet the common-frequency cutoff, so many answers will feel obscure.
• OOZES, OUZOS, ORZOS, and OXIMS each score 14 points in Scrabble.

How many 5-letter words start with O and end with S?

There are 74 matches. Collins contains 73, NWL2023 contains 53, and ENABLE contains 49; those totals overlap because many words appear in more than one dictionary. Don’t add the three counts to estimate the number of distinct plays.

The familiar end of the set includes OPENS, OVENS, OATHS, OMENS, and OBEYS. OASIS and OASES both fit, but they are separate entries, so check the letters in your rack rather than treating one as a variant of the other.

The average score is 7.8 points, while the four highest-scoring entries reach 14. OOZES is the standout you are most likely to recognize; OUZOS, ORZOS, and OXIMS are less familiar options at the same score.

How should you use these O-first, S-last words?

Start by testing common-looking fits such as OPENS, OVERS, and OASIS, then widen your search if those letters do not match. Only four entries fall into the common-frequency group, so an unfamiliar candidate is not automatically invalid. The list includes 65 entries with definitions, but a definition alone does not guarantee acceptance in your game.

For Scrabble, OOZES has the same 14-point base score as OUZOS, ORZOS, and OXIMS before board bonuses. The recognizable word is not always the strongest play: consider where you can place the high-value letters, not just how familiar the word looks. The 74-word total combines several dictionaries, so check your game’s specific word list before committing.
