I am confused by "wilt" and "kunt". The tips show these as the proper conjugation for U and when speaking formally (if I am understanding the tips correctly). In another sentence we had: Jij kunt ook koken, als je wil. From this I guessed that the -t form might be used frequently with emphasized pronouns, so I was surprised to see Zij wil instead of Zij wilt. Can someone please help me sort through the confusion for these two verbs?
