6-letter words with X as the 4th letter and S as the 6th letter

The shared ending does not make this a simple plural list: all 39 matches end in S, but their stems vary widely. None is marked common, while 31 are marked defined. PRAXIS and PLEXUS are easy anchors; many other entries are specialist forms or less familiar inflections.

At a glance the pattern and its strongest clues

• There are 39 matches with X fourth and S last.
• All 39 end in S.
• No matches are marked common; 31 are marked defined.
• JYNXES and VAXXES tie at 23 points.
• P is the most frequent first letter, with 7 matches.

Are all of these S endings simple plurals?

No. The final S appears in familiar forms such as HOAXES, FLUXES, FLEXES, and COAXES, but the group also contains PRAXIS, PLEXUS, and DEIXIS. A fixed final letter describes the pattern; it does not tell you how a word changes grammatically.

The opening spread begins with P at seven matches, F at five, and O at four. C, D, and R each begin three. This distribution offers a useful scan order, while the shared ending confirms the last tile immediately.

JYNXES and VAXXES both score 23 points, with DOXXES at 21 and JINXES at 20. The next listed tier is PTYXES and PTYXIS at 18. These unusual high-value spellings are strongest as score references, not as words to assume every opponent will know.

A practical limit: no match is classified as common, so the list leans heavily toward tournament vocabulary. Check your game’s word list before playing a rare entry. A common mistake is calling every final S a plural; PRAXIS and DEIXIS make that shortcut unreliable.

The E-fourth, S-last frame is much larger, showing how strongly the X position constrains this group. Keeping both fixed positions in view makes candidate checking faster. Start with familiar forms such as PRAXIS, HOAXES, and FLUXES, then consider less common spellings carefully.

A final S can tempt players to assume a plural, yet this set includes nouns and other forms as well. Read the whole word rather than inferring its grammar from the last square.
