A goaltender is a crucial position in ice hockey, where the primary task is to defend their team's goalpost. In addition to the popular term 'goaltender,' this position is often referred to as the 'goalie' or 'netminder.' In the NHL, they are sometimes called the 'tendy,' 'keeper,' or 'backstop.' In international ice hockey, the terms 'guardian' and 'custodian' are commonly used, while in roller hockey, the term 'goaler' is often used. These synonyms are often interchangeable with the term 'goaltender,' and while they all refer to the same position, the term used often depends on the region and league.
