Very easy. A dynamic programming language is characterized by late binding
features. For instance, type is principally a run-time property of
values/objects, rather than of pieces of program source code. Functions and
types may defined and redefined while the program is running.  These
capabilities would be a bare minimum.  Dynamic languages also usually exhibit
introspection: various entities that describe the program, and which disappear
after compile time in static languages tend to be available in a useful
run-time representation in dynamic languages. For instance "class"
or "variable name" might be strictly compile-time concepts in a static
language, but in a dynamic language they might be run-time values of some
sort.
