What word am I looking for?

[TheOtherBennetSister]

It can be applied to a forest that is too densely packed to easily pass though, and also to a text that is too complex and difficult to be easily understood.

Impenetrable?

Dense? Opaque?

Yeeees - maybe impenetrable. That would definitely work. Thank you.

I think there's another word though. I might be wrong.

Indecipherable?

Unfathomable?

Unnavigable

Impermeable?

Megamind voice?

Huh?!

Definitely impenetrable.

Inaccessible.
Impassible.
Unnavigable.

Impermeable.

Untraversable
Unintelligible
Obscure

Not impermeable. That relates to fluids.

Impregnable.

Sesquipedalian.

I'm going to use impenetrable. Thanks all!

Inscrutable could apply to the book (but not the forest).

Thank you Pleiades - that's useful.

A thesaurus is what you need

I bought one but the pages are blank

I'm lost for words

Sorry... 🚕

Thicket?

I think it's a mistake not going with "dense".
