Lineups are commonly used in sports and other competitive activities. A lineup is a list of players or participants who are taking part in a game or event. The term lineups can be broken down into three words: SLATES (6 letters), arrays (6 letters), and ROSTERS (7 letters). SLATES refer to the list of players or participants, while arrays refer to the order in which they are listed. ROSTERS refer to the group of players or participants that make up the lineup.
