- polecenie (noun) = recommendation. errand
- polecić (-cę -cisz) (pf), (impf) polecać +Acc (+Dat) = recommend. entrust something (to someone)
Here, the demonstrative pronoun should be “tę” rather than “tą”.
Using tą (the instrumental form) in place of tę (the accusative form) is, sadly, a common error among Polish native speakers.
Thanks, I’ll report it next time around. It’s funny, I was looking at that sentence and thought there was something wrong with it but I couldn’t quite put my finger on it!
