What is meant by the word "shanāʾan" in the noble verse (and let not the hatred of a people prevent you from being just), and the word "shāniʾuka" in the verse (Indeed, your enemy is the one cut off)?

The Almighty's saying: "O you who have believed, be persistently Qawwameen (firm upholders) for Allah, witnesses in justice, and let not the hatred of a people prevent you from being just. Be just; that is nearer to righteousness." (Qur'an 5:8) This means to be just in testimony and let not your hatred of a people drive you to abandon justice with them. So, Ash-Shanaan (الشنآن) is hatred.

And the Almighty's saying: "Indeed, your enemy is the one cut off." (Qur'an 108:3) This means that the one who hates you, O Muhammad, and hates your guidance and your religion, is the one whose ذكر (remembrance/legacy) is cut off. This verse was revealed in response to the polytheists who said that Muhammad was cut off (abtar) after the death of his male children.
