Particularizers are a category of adverbs that focus attention on what follows them, without excluding other possibilities. We are interested in finding more advanced chunks that they are found with.  Firstly, we look at the levels given by the English Vocabulary Profile:

especially = A2 very much or particularly

largely = B2 almost completely

mainly = B1 mostly or to a large degree

mostly = B1 mainly or most of the time

particularly  = B1 especially, or more than usual

predominantly = C2 mostly or mainly

primarily = B2 mainly
