Type 3 noun suffixes express the speaker's attitude towards the noun or how sure the speaker is about the noun's accuracy. These suffixes add meaning about belief, doubt, or irony.

-qoq (so-called)

This suffix shows irony or doubt about the noun's legitimacy. It implies that the speaker does not fully trust what the noun describes. For example:

• roj – peace → rojqoq – so-called peace (indicating doubt about the peace being real or lasting)

Using -qoq may express skepticism, sarcasm, or disapproval of what the noun stands for.

-Hey (apparent)

This suffix means the speaker thinks the noun is likely correct, but there is still some uncertainty. It is used when something is detected but not confirmed. For example:

• Duj – vessel → DujHey – apparent vessel (it looks like a vessel, but it's not certain yet)
• HoS – strength → HoSHey – apparent strength (the strength is assumed but not confirmed)

If a ship's scanner picks up an unknown object, and the officer believes it may be a ship but isn't certain, they might call it DujHey.

-na' (definite)

This suffix is the opposite of -Hey. It means full confidence and certainty that the noun is the correct description. The speaker has no doubt.

• Duj – vessel → Dujna' – definite vessel (there is no question it is a vessel)
• DevwI' – leader → DevwI'na' – definite leader, true leader (a leader without question)

When a Klingon officer becomes sure the object on the scanner is a vessel, they would say Dujna' instead of DujHey.
