There's no noun suffix that functions like the verb suffix -qu', which emphasizes or highlights whatever immediately precedes it. In other words, there are no "rover" suffixes for nouns. Noun suffix placement is always fixed.

For example, Dujmeyna' means "definitely ships" or "undoubtedly ships." Even though -na' follows -mey, it doesn't necessarily emphasize plurality itself.

However, there's a subtlety here. The word jaghpu'na' could mean "definitely enemies"—there's no doubt they're enemies rather than friends or neutral parties. But in the right context, it can also emphasize plurality: "definitely (several or many) enemies."

Consider the following conversation:

In the second speaker's response, -mey explicitly marks plurality, while -na' emphasizes the certainty of that plurality — there is definitely more than one ship.

This nuance doesn't apply to possessive suffixes. For instance, jaghna'lI' means "definitely your enemy," emphasizing the certainty of the enemy's status, but it doesn't mean specifically "your enemy (as opposed to mine)."

If you want to emphasize the possessor specifically, use vocal stress (spoken emphasis) rather than suffixes. For example, pronounce DujlIj ("your ship") with stress on the suffix: DujlIj.
