Word puzzle glossary
Twenty-five terms every word-puzzle player encounters — from anagram to word square, with plain-English definitions and concrete examples. If you play Wordle, LexSweep, Crosswordle, or the NYT crossword, this is the vocabulary you already use without thinking about it.
Word-puzzle terminology has accumulated over centuries — from Victorian-era word squares to 21st-century daily puzzles. Knowing the names makes pattern recognition easier: spotting that today’s Wordle answer is an isogram tells you instantly that every letter is unique, which dramatically narrows the guess space.
1. Anagram
A word formed by rearranging the letters of another word.
Example: LISTEN ↔ SILENT
2. Palindrome
A word, phrase, or sequence that reads the same forwards and backwards.
Example: LEVEL, RACECAR, MADAM
3. Lipogram
A piece of writing that deliberately avoids a specific letter.
Example: Gadsby (1939) — a 50,000-word novel with no letter E
4. Word square
A grid where rows and columns spell the same words (a "symmetric" square) or different valid words.
Example: LexSweep uses 5×5 symmetric word squares.
5. Ambigram
A word designed to be read the same way from multiple orientations.
Example: The Angels & Demons book cover; the SWIMS ambigram (rotates 180° to read SWIMS).
6. Kangaroo word
A word containing letters of another word, in order, that share its meaning.
Example: MASCULINE contains MALE; ENCOURAGE contains URGE.
7. Heteronym
Two words spelled identically but with different pronunciations and meanings.
Example: LEAD (metal) vs LEAD (to guide); TEAR (rip) vs TEAR (cry).
8. Homophone
Words that sound alike but are spelled differently.
Example: THEIR / THERE / THEY'RE; TWO / TOO / TO.
9. Pangram
A sentence using every letter of the alphabet at least once.
Example: The quick brown fox jumps over the lazy dog.
10. Acrostic
A poem or text where the first letter of each line spells out a word or message.

How LexSweep uses these terms
LexSweep’s mechanic is a symmetric word square — five 5-letter words arranged so that row i reads the same as column i. The puzzle pool we draw from contains many isograms (words with no repeated letters — these are popular openers like CRANE, SLATE, RAISE), plus a healthy share of more challenging puzzles featuring palindromic or repeated-letter words.
