Dynamically typed language is called so because the type is associated with run-time values. You don’t have to specify types every time.

If the enclosing  Feb 14, 2019 Unless notified otherwise, methods returning one or more dynamically-typed values use a common API pattern, in which the caller passes in  C# - Dynamic Types. C# 4.0 (.NET 4.5) introduced a new type called dynamic that avoids compile-time type checking.

Dynamically typed languages don't check types until execution, and that line never executes. Dynamic type checking is the process of verifying the type safety of a program at runtime. Implementations of dynamically type-checked languages generally associate each runtime object with a type tag (i.e., a reference to a type) containing its type information.

This means that scripts written in dynamically-typed languages (like Groovy) can compile even if they contain errors that will prevent the script from running properly (if at all). A programming language is said to be dynamically typed if the programmer doesn’t have to assign a type explicitly, and a type isn’t assigned to the variable until run-time. This means that with languages that use dynamic typing, you don’t actually have to decide if the variable you’re creating should be a Double or a Float or a String For example, in dynamically typed languages, if you’re not careful with sanitising user input, you can end up doing weird stuff like (for example) trying to add a number 10 with the string “8” and you would get the string “108” as a result instead of the number 18 that you were expecting. Advantages of dynamically-typed languages: Dynamic Typing. Python is a dynamically typed language.
