Clearance
A move — often a sacrifice — that vacates a square or line so another piece can use it.
A clearance sacrifice throws away material for one reason: a friendly piece is standing on the square or line you need. Get it out of the way — with tempo if you can — and the real threat lands.
The cousin of clearance is the decoy (which lures an enemy piece) and deflection (which drags a defender away). Clearance is about your own pieces getting out of their own way.
Many combinations only work after a quiet clearance move. Training yourself to notice 'my own piece is in the way' unlocks tactics you'd otherwise miss.
Calculating a beautiful mating net and forgetting that your own rook blocks the file the queen needs.
