A weekly typed language is one that considers types to be more or less views on the same thing, for instance a weakly typed language will let you do 1+"1", which would ether be equal to "11" or "2" (depending on the language semantics), compared to a StronglyTyped Language which would raise a type error.

Compare: StronglyTyped

Not to be confused with StaticallyTyped or DynamicTyping
