Sometimes it helps to analyze the contexts in which a particular particle is used to ascertain its meaning, other times it's just better to memorize a phrase outright, such as について = "about"
If you ignore the English translation, in literal Japanese something somethingにつく means to attach to something or adhere to something, so strictly speaking the に used here is the　に equivalent to "to" though I don't recommend memorizing it that literally.
