"Przyniosłem mojej żonie obiad."

Translation: I brought my wife lunch.

[conor.raff]

Sort of an inbetween one (regular in the endings at least, like everything), declines like its root: "nieść"

"With nieść and móc, the o of the stem becomes ó in the third-person singular masculine. With nieść, the o of the stem becomes e in the masculine personal plural."
