Queenside majority structure
A pawn structure where one side has more pawns on the queenside than the opponent, such as three against two, and can create a passed pawn there while the other side holds a kingside majority.
A queenside majority appears when the pawn trades leave one side with more pawns on the a- to c-files. A classic case is the Grunfeld Exchange: after ...cxd4 and cxd4, Black has a- and b-pawns against White's lone a-pawn, while White keeps an extra pawn in the center.
The majority is valuable because it can produce a passed pawn, especially in endgames. The normal plan is to advance the pawns carefully, create a healthy passed pawn with support from the king and pieces, and keep the majority mobile. A crippled majority is a different story: in the Ruy Lopez Exchange, Black's extra queenside pawn is a doubled c-pawn, and that majority cannot force a passed pawn on its own.
The other side has its own majority in the center or on the kingside, so the question is who makes progress first. The queenside side wants a passed pawn far from the kings; the other side wants to use its central or kingside pawns before that passer runs.
Common errors are advancing the pawns too early, leaving weaknesses behind them, and allowing the other side to blockade the passed pawn. A practical tip is to push the pawn that has no opposing pawn in front of it first, use the pieces to support the advance, and trade into an endgame where the majority is the deciding factor.

Compare it with Carlsbad structure. The pawn setup from the Queen's Gambit Declined Exchange Variation, with White pawns on d4 and e3 against Black pawns on c6 and d5, where White often launches a queenside minority attack with b4 and b5.
