7-letter words with X in the middle

There are 66 of them, out of 33,296 7-letter words in total, so roughly 0.2% of all seven-letter words carry X in their centre slot. That ranks it 26th out of 26 for this slot, so X in the middle is a genuinely narrowing clue. A short list here is good news.

The 4th one. A seven-letter word has 3 letters before the centre and 3 after it, so there is exactly one middle slot with no ambiguity. Even-length words have two centre letters and no single middle, which is why this page only covers 3, 5, 7, 9 letters.

Crossings. In a crossword, an intersecting entry hands you one letter in the middle of a 7-letter slot far more often than it hands you the first or the last. Scrabble does the same when you build through a tile already on the board.

Among 7-letter words with X in the centre, the most common opening letters are A (12), F (10), D (7), and the most common final letters are S (24), E (13), L (8). Scanning by first letter is usually the quickest way through a list this size.

No. Only standard dictionary words appear, which is the same standard Wordle, Scrabble, and crossword grids apply. Missing words are almost always names, hyphenations, or abbreviations.
