You're staring at the grid. The black and white squares are mocking you because you’ve got the first two letters and the last one, but the middle is a void. The clue is crossword clue heart of the matter. It feels like it should be easy. It feels like the answer is right on the tip of your tongue, but your brain keeps cycling through "essence," "center," "middle," or maybe "core."
Crossword puzzles are basically psychological warfare played with a pen.
When a constructor puts "heart of the matter" in their list, they aren't usually looking for a poetic description of a person's feelings. They want something punchy. They want a word that fits into a tight corner of the Friday New York Times puzzle or a quick LA Times midday break. Usually, the answer is NUB or CRUX. Sometimes it’s CORE. If you’re really unlucky and the constructor is feeling fancy, it might even be MARROW.
Breaking Down the Common Answers
The most frequent culprit is NUB. Three letters. It's the ultimate filler word for constructors because that "B" is easy to cross with words like "BATH" or "BOATS." In common English, we talk about getting to the nub of an issue. It’s the small, essential piece that remains when you strip away all the fluff. Honestly, it’s a weird word when you think about it too long. It sounds like a physical thing—like a little bump on a tree—but in the world of crosswords, it’s almost always metaphorical.
Then you have CRUX. This is the one that shows up when the puzzle wants to feel a bit more "intellectual." It comes from the Latin word for cross. It’s the point where everything intersects. If you see a four-letter space and the clue is "heart of the matter," your pencil should be hovering over the letters C-R-U-X.
But wait. What if it’s four letters and CRUX doesn't work? Check the crosses. If you have an "O" in the second position, it's CORE. It’s the most literal interpretation. The core of an apple is the heart of it. The core of an argument is the heart of it. It’s simple. Maybe too simple for some of the harder puzzles later in the week, but it’s a staple for a Monday or Tuesday grid.
Why Do These Clues Feel So Tricky?
Context is everything. The English language is a mess of synonyms, and crossword editors like Will Shortz or Patti Varol know exactly how to use that against you. A clue like "heart of the matter" is what we call a "definitional" clue. It’s not a pun. There’s no question mark at the end to tell you there’s a joke involved. It’s a straight-up request for a synonym.

The difficulty comes from the Letter Count.
- 3 Letters: NUB
- 4 Letters: CORE, CRUX, GIST
- 5 Letters: BASIS, FOCUS
- 6 Letters: KERNEL, CENTER
- 7 Letters: ESSENCE
Take GIST. It's a great word. You get the gist of a story, which means you’ve reached the heart of the matter. But constructors use GIST less often than CRUX because the letters in CRUX are more "expensive" in Scrabble points and often harder to weave into a grid. When a constructor manages to fit a "X" or a "Z" into a corner, they’re showing off.
The Weird History of "The Heart" in Puzzles
Crosswords haven't always been about these short, punchy synonyms. Back in the early 20th century, clues were often much more verbose. But as the "American style" of crosswords evolved—where every single letter must be part of both a horizontal and vertical word—brevity became the king of the grid.
KERNEL is a fascinating one. It’s the "heart" of a nut. If you’re doing a puzzle with a botanical theme, or if the constructor is trying to be slightly more clever, they’ll go with KERNEL. It’s a bit of a "lateral thinking" answer. You aren't looking for a metaphorical heart; you're looking for a literal one that lives inside a shell.
Real Examples from the Archives
Let's look at some specific instances where this has popped up recently. In a New York Times puzzle from a few months back, the clue was simply "Heart of the matter." The answer? Nitty-gritty. That’s a long one. Eleven letters. That’s not a filler word; that’s a "seed" entry. A seed entry is a long, interesting phrase that the constructor builds the rest of the puzzle around.
If you’re looking at a Sunday puzzle—those giant 21x21 grids—you might see MEAT AND POTATOES. It’s the same concept. The heart of the matter. The substance. The stuff that actually fills you up.

I remember once seeing the clue "The very heart of the matter" and the answer was INMOST. It felt like a betrayal. "Inmost" describes a location, sure, but it felt a bit clunky compared to the elegance of CRUX. That’s the thing about crosswords; you have to be ready for the constructor's personality. Some are elegant. Some are "crunchy" (meaning they use lots of hard consonants). Some are just plain annoying.
How to Solve it Every Time
You've got to look at the "crosses." This is Crossword 101, but people forget it when they're frustrated. If you have "heart of the matter" and you're stuck between NUB and something else, look at the vertical clues intersecting those squares.
If the first letter of your answer is also the start of a vertical clue like "Opposite of 'Pro'," you know the first letter is "C" for "Con." That immediately points you toward CORE or CRUX. If the second letter intersects with "A shape for a pyramid base," you’re looking at an "S" for "Square," which doesn't help much, does it?
Actually, let's try a better example. If the third letter of your four-letter answer intersects with "Tavern order," the answer is likely "ALE" or "BEER." If it’s "ALE," the third letter is "E," making your answer CORE. If it’s "BEER," the third letter is "E" as well. Okay, bad example. But you see the point. You have to play the percentages.
Misconceptions About Synonyms
A lot of people think that "heart of the matter" should always result in the word ESSENCE. It’s a beautiful word. It feels right. But in my experience, ESSENCE is actually quite rare for this specific clue. Why? Because it’s seven letters long and has four "E"s. In the world of crossword construction, too many "E"s can actually make a grid harder to build because it forces the constructor to use certain types of words in the crosses.
Also, don't confuse "heart of the matter" with "heart of the city" or "heart of the forest."

Pro Tips for the Avid Solver
Honestly, if you want to get good at this, you should start keeping a mental (or physical) list of "Crosswordese." These are words that appear in puzzles way more often than they do in real life. NUB is a classic piece of Crosswordese. When was the last time you actually said the word "nub" in a conversation? "Hey Steve, let's get to the nub of this budget report." You’d sound like a character in a 1940s noir film.
But in a puzzle? NUB is gold.
Another tip: check the tense and the pluralization. If the clue was "Hearts of the matters" (which would be a weird clue, but stay with me), the answer would have to be plural. NUBS or CORES. The clue and the answer must always match in part of speech and number.
Actionable Steps for Your Next Puzzle
- Count the squares immediately. Don't even think of a word until you know if you need 3, 4, or 7 letters.
- Check for "C" or "N" starts. The most common answers (CRUX, CORE, NUB) start with these. If you have a "C" from a cross, you’re 80% of the way there.
- Look for the "X". If you're doing a Thursday, Friday, or Saturday puzzle, the constructor is more likely to use CRUX because the "X" adds difficulty and flair.
- Don't marry your first guess. If you wrote in GIST but the vertical clue for the "G" is "A type of fish" and the answer is clearly CARP, erase GIST. It's not working.
- Use a pencil. This sounds obvious, but the psychological freedom of being able to erase a wrong guess like BASIS when it should have been FOCUS is huge.
Crosswords are supposed to be a relaxing challenge, not a source of high blood pressure. Next time you see crossword clue heart of the matter, you won't be the one scratching your head. You'll be the one filling in CRUX with the confidence of a person who knows exactly how the game is played. Happy solving.
