恥ずべき is listed as an adjective in EDICT, as a 'compound word' (連語) in kotobank
([here](https://kotobank.jp/word/%E6%81%A5%E3%81%9A%E3%81%B9%E3%81%8D-358568#E5.A4.A7.E8.BE.9E.E6.9E.97.20.E7.AC.AC.E4.B8.89.E7.89.88)),
and as a "noun or verb acting pre-nominally" on the Midori app. My question
relates to a sample sentence I saw on EDICT
([link](http://nihongo.monash.edu/cgi-
bin/wwwjdic?1Q%C3%D1%A4%BA%A4%D9%A4%AD_1_)).

> > 君は、自分の愚かさを恥ずべきだ。You should be ashamed of your folly.

All the other examples I found are `恥ずべき+Noun` (恥ずべき秘密, 恥ずべき行為, 恥ずべきこと, etc),
making them noun phrases. But in the above example 恥ずべき is followed by the
copula だ. Also, the inclusion of the particle を would seem to make it a verbal
use of 恥ずべき since there is no other verb present.

So is that example sentence correct? If so, how is 恥ずべき functioning
grammatically with を and the copula だ?

question
grammar nominalization
What word class is 恥ずべき?
「恥ずべき」 is a combination of the verb **恥ず** and the auxiliary verb **べし**.

<https://ejje.weblio.jp/content/%E3%81%B9%E3%81%97>

Both of these words follow somewhat archaic grammar patterns, so they don't
behave like most modern verbs.

  * 恥ずべき functions with を because it is a verb taking a direct object

  * 恥ずべき functions with the copula だ because べき is the form of the auxiliary verb べし that attaches to the copula
