"Stick to your principles".

Question

Is to your principles an adjectival or adverbial or verbal phrase? Or none of the above?? Can you please help me turn it into one of the phrases mentioned above. THAAAAANKS :D

I don't see an adverb. All you have is the verb, "Stick," as a command. It is modified by a prepositional phrase, "to your principles."

I hope this helps. Thanks for asking.
