Here are some examples:
* Chlorine: From the root "chlor" (meaning green)
* Caffeine: From the root "caffe" (referring to coffee)
* Discipline: From the root "disciplin" (meaning to teach)
* Medicine: From the root "medic" (referring to healing)
However, there are exceptions to this rule. Sometimes "-ine" can be added to form an adjective or even a verb, but these are less common.
It's important to note that the specific part of speech will depend on the root word and the context in which it is used.
