> both are dynamic languages with types added later in?
Common Lisp has always had types and type declarations (e.g. `the` in the hyperspec[1]) as it's part of the specification. It was not added later as far as I know.
However, `declaim` and `declare` were left very underspecified so they tend to be very implementation-specific, though there are libraries that make types more portable[2][3].
