A person who confers or bestows something
A person who, or thing that, constructs.
A company or individual who builds racing vehicles. In Formula One, constructor status is strictly defined by the rules, but in other motorsports the term is merely a descriptor. Depending on the racing rules, some constructors (e.g. Cosworth) may provide vehicles to racing teams who are not themselves constructors, while others are both teams and constructors (Ducati Corse, Scuderia Ferrari).
A class method that creates and initializes each instance of an object.
