Quick guide
How it works
Turn this unit’s vocabulary into a printable crossword puzzle. Type each term with its definition — one a line, as “term | definition” — and the generator interlocks the terms into a numbered grid and prints your definitions as the Across and Down clues. Start from a ready-made science, maths or geography list, or paste your own. Download the result as an A4 or US Letter PDF with an answer key.
Paste your terms and definitions, preview the grid instantly, then download the PDF — no account needed.
Choose a subject list to start from, or type your own terms and definitions one per line as “term | definition”.
Pick a difficulty — it sets the square size, the first-letter hints and the word bank, and never touches your terms.
Download the PDF with its answer key, or copy a share link that restores these settings.
Teaching tip
Using these worksheets in teaching
A vocabulary crossword asks for something a matching exercise does not: the student reads the definition, retrieves the term, and then has to spell it into a fixed number of squares with every crossing letter agreeing. That last step is what turns recognition into recall — a term a class can pick out of a list is not yet a term they can produce. Use it as the second pass over a unit’s words rather than the first, once the definitions have been met at least once, and print the word bank for a class meeting the terms for the second time and no bank for the third.
Frequently asked questions
How is this different from the crossword maker?
Mechanically it is the same puzzle; what differs is the job and the wording around it. The crossword maker asks for an answer and a clue, which is what a puzzle setter writes. This page asks for a term and a definition, which is what is already in a teacher’s vocabulary list — so a list written for a spelling test or a glossary can be pasted straight in without rewriting it as clues. There is also no word-count control here: a vocabulary list is the list, not a pool to sample from, so every pair you type is in the puzzle.
Do I have to write a definition for every term?
No. Leave the pipe off a line and the letter count is printed in its place, so a list of terms can be typed first and defined later. A term with no definition still gets a numbered entry and still crosses the others — it just gives the class less to go on.
What makes a good definition for a crossword clue?
One that identifies the term without containing it. “The force that pulls objects toward the Earth” works; “gravity force” does not, because the answer is printed inside its own clue. Keep it to a line — the clue lists are set in two columns by default, so a definition longer than about a hundred characters starts to crowd the page.
Can I use the same list for more than one sheet?
Yes, and it is worth doing. Press regenerate and the same terms interlock into a different grid, so a class that saw the puzzle on Monday cannot solve Friday’s from memory of where the words went. Turn the word bank and the first-letter hints on for the first pass and off for the second.
Why does it say a term could not be fitted?
Every term after the first has to cross one already on the grid, sharing a letter in a position that is still free. A term whose letters appear nowhere else in your list has no legal place, so it is named in a notice rather than forced in. Add a term that shares a letter with it, or press regenerate to try a different arrangement — the puzzle without it still prints and is still valid.
Is there an answer key?
Yes. The completed grid prints on a second page of the same PDF, so you can mark the sheet without solving it yourself.
