Hello! What’s the difference between this and “beki”? Thank you!

ことだ
This grammar point is a combination of こと and .

[Authoritative; used by someone of higher status/power/attitude]

[ことだ is used when giving indirect advice]

べき
べき originates from the conjugative form of べし, an auxiliary verb that attaches to the plain form of a verb, but 〜べき it can be like a noun since it can be followed by だ/です.

Unlike ことだ it doesn’t attatch to the negative form of verbs. Instead you can do something like …べきじゃない.

[Used to express a strong sense that doing something is generally a correct thing to do, an obligation, a duty, etc.]

[Much stronger than した方がいい]

説明してくれてありがとうございます!So ~ことだ is more authorative in use than “べき”, basically? And can also be used for giving indirect advice. Did I get it right?

@Elibean
To sum it up, べきだ usually expresses general obligation so it sounds more authorative, while ことだ usually expresses personal advice/warning.

Cheers!
