13 Letter Words: Compare Forms and Crossings

Use Thirteen Squares to Test a Specific Hypothesis

A long answer can look convincing before it fits every crossing. This page searches 10,321 selected thirteen-letter entries, allowing you to test a proposed beginning, ending or position pattern against the same collection. The results establish spelling matches, not the intended meaning of a puzzle clue.

Keep confirmed crossings separate from a guessed word family. If you think the answer ends in TION, try that as a reversible condition. Do not remove a reliable crossing simply to preserve an attractive guess.

Compare KNOWLEDGEABLE with KNOWLEDGEABLY

Enter KNOW in Starts with and select Find Words. The collection returns 3 KNOW-starting spellings. Add LEDGE in Contains sequence to compare KNOWLEDGEABLE and KNOWLEDGEABLY. Both contain thirteen letters and share their first twelve positions. Their final letters distinguish an adjective from an adverb.

For a clue describing an informed person, KNOWLEDGEABLE may fit the required grammar. A clue describing how someone spoke may instead call for KNOWLEDGEABLY. With KNOW and LEDGE applied, enter LE in Ends with to keep the first spelling, or LY to keep the second. The clue still decides whether either is appropriate.

Make the Decisive Crossing Visible

The pattern KNOWLEDGEABL? retains both forms. Replacing the last unknown with E isolates KNOWLEDGEABLE; replacing it with Y isolates KNOWLEDGEABLY. This is a useful example of a final crossing doing more work than an already established beginning.

Contains sequence LEDGE also retains both entries. It requires those letters next to each other in that order. Reversing them to EGDEL does not describe the same condition and returns neither spelling.

Distinguish a Suffix Search from a Grammar Decision

The TION shortcut finds 554 entries in this collection. It is a starting point, not a prediction that your answer has that ending. A noun clue may justify investigating the group, but its definition and crossing letters must still separate the possibilities.

Other endings can reveal different forms. Compare the ING shortcut with a particular clue's tense rather than assuming any matching ending is enough. These counts describe this selected reference; they are not measurements of English usage frequency or an official puzzle answer pool.

Build a Pattern Without Shifting the Later Letters

A nonempty pattern must contain exactly thirteen positions. Each ?, _ or . represents one unknown square. An omitted unknown shifts every following letter; a twelve-position pattern receives a length warning instead of a partial match.

Patterns combine with all the other fields. Starts with KNOW and Exclude K contradict one another and produce no results. Exclude applies anywhere in a candidate, so it should contain letters you know are absent rather than letters that merely occupy the wrong position.

Respect What the Fields Cannot Express

There is no separate misplaced-letter field, rack inventory or minimum-copy control. The finder can fix repeated letters at known positions, but it does not check whether your tiles supply them. Letter fields remove nonletters; pattern cleanup retains letters and the three unknown markers. Punctuation is not interpreted as a choice between alternative letters.

Keep Applied Filters and Unsubmitted Edits Apart

Find Words or Enter reads the text fields and selects All in the alphabet strip. Editing a field alone does not update the results. Initial buttons then narrow the applied conditions without deleting them.

Changing Sort orders the previously applied search; it does not read an unsaved field edit. Submit your new condition first. Clear Filters empties every field, returns to All and restores A–Z.

Quick-pattern buttons reset the earlier conditions and sort before applying their own search. Their counts show the number of matching entries, and the green highlight marks the chosen shortcut. They are fresh starting points rather than additional restrictions on your previous query.

Understand the Two Result Layouts

All/A–Z without text conditions groups results by initial. A filter, an individual initial or a different sort produces a flat grid. Results appear in pages of 48 words. Use Previous, Next, numbered pages or Go to page below the tiles. Changing an applied filter, initial or sort returns to page one. Tiles display spelling and base points, but clicking a tile does not copy it.

Check Why the Two KNOW Forms Have Different Totals

KNOWLEDGEABLE totals 24; KNOWLEDGEABLY totals 27. The shared twelve-letter portion totals 23. Adding E contributes one point, whereas adding Y contributes four. This isolates the reason for the three-point difference without treating word length as a score predictor.

These are printed-letter totals using the implemented English tile values. The calculation does not substitute zero for a blank tile or account for board premiums, existing letters, cross-words, bonuses or legal placement. Highest score ranks these base totals and resolves ties alphabetically.

A high-scoring entry is not automatically usable in your game. Confirm the relevant lexicon and the board situation separately; this reference is not a move validator.

Resolve an Empty Search Before Expanding the Task

Check pattern length, conflicting exclusions and any selected initial first. Remove one uncertain condition and submit again. Remember that Contains means adjacency, not rearrangement. If your confirmed evidence still gives no match, the spelling may be outside the 10,321-entry collection.

For a larger positional reference, try the Crossword Solver. For rearranging supplied letters, use the Anagram Solver; for rack searches and blank-aware base totals within its input limits, use the Scrabble Helper.

For words made from some of your supplied letters rather than the whole set, use the Word Unscrambler.

If the square count changes, compare the twelve-letter reference. The Word Lists hub helps you choose other lengths instead of forcing a candidate into the wrong space.

Reference Scope and Verification

On 27 October 2026, the embedded list was checked for uniqueness and exactly thirteen A–Z letters. The KNOW examples, exact patterns, adjacency rules, conflicting conditions and 24/27-point calculations were tested. The expanded list is selected from the English Speller Database (ESDB), release 2026.02.25: level-80 US, British, Canadian and Australian spellings, variants up to 1, default categories and no abbreviation part-of-speech entries. Only lowercase A–Z thirteen-letter source spellings were retained. Read the source notices and license. This is a verification date, not a dictionary revision or certification of every definition.
