Manual does not mention dictionary.el

[Petteri Hintsanen]

I was wondering if Emacs could do dictionary look-ups.

After failed search through the manual (for "dictionary") I resorted to
a web search.  It quickly showed that Emacs has included dictionary.el
since version 28 or so.

Why this extremely useful feature is not mentioned in the manual at all?
Or did I just miss it somehow?
