Hortatory

I looked up "hortatory" on Merriam-Webster Online.

The entry gave no definition but 2 other words: "hortative" and "exhortatory."

"Hortative" = giving exhortation
"Exhortatory" = using exhortation

Really helpful. Really.

So I clicked through to exhortation.

Definition 1: an act or instance of exhorting

Great. Thanks. (To their credit, definition 2 was "language intended to incite or encourage", but that's not the first definition!)

Finally, clicking on "exhorting" led me to exhort and a real definition. All that work to find out the exact definition of hortatory! Can't they make it any easier? Can't they make it so that I don't laugh when looking up words?
