"Secondarily" is an adverb that describes something that is less important than the main thing. For example, if you are talking about your job, your main responsibility might be to answer customer calls, but then you could say "secondarily, I also help with filing paperwork." This means that answering calls is the most important thing you do at work, but doing paperwork is also something you do, just not as important.
