Crossword Clue: Organ that controls thought
Here's the answer to the Organ that controls thought crossword clue, with an explanation and where it has appeared.
Definition & answer: BRAIN
BRAIN solves the clue "Organ that controls thought". Spanning 5 letters (2 vowels, 3 consonants), it begins at B and ends at N. Like most crossword fill, it lives at the intersection of two words, so a single confirmed crossing letter frequently reveals the whole entry.
Origin & meaning
The brain is the control center of the nervous system, containing tens of billions of neurons. Despite using only about 20 watts of power, it consumes a fifth of the body's energy.
Common usage
Brain turns up often in crosswords because of that letter mix. Words like BRAIN interlock cleanly with longer entries, so constructors reach for them to make a grid fit together without awkward clashes. Given a 5-square slot and a crossing letter or two, it's usually quick to confirm.
Crossword trivia
At 5 letters, BRAIN shows up in daily mini and themed puzzles far more than longer, obscure words. It's the kind of entry worth memorizing — the more common short words you know cold, the faster you solve.
Stuck on this clue?
If this clue won't come, leave it and fill the answers that cross it. Once a couple of BRAIN's letters are locked by neighboring words, the entry tends to reveal itself. Crossings beat staring at a clue every time.
