This is the 7621st most frequent Polish word.
lenę
"Lenę" is not a standard Polish word. If you meant "lenię," it is derived from "lenić się," meaning "to be lazy" or "to idle."
Here, 'lenę' is used to express being inactive or lazy—commonly derived from 'lenić się', which means 'to be lazy'.
Od rana lenę i nie mogę zebrać się do pracy.
Since morning, I've been lazy and can't gather myself to start working.
In this case, 'lenę' refers to the activity of cultivating linen (textile plant); this more formal usage is less common in modern Polish.
Codziennie uprawiam lenę, obserwując rośliny w ogrodzie.
Every day, I cultivate linen, observing the plants in the garden.
Here, 'lenę' is part of a phrase relating to the material 'len' (linen), used to specify cloth material.
