theres really nothing unclear about that sentence as long as you understand the definition of the word "commonly"

from google:

com·mon·ly
/ˈkämənlē/ {| class="vk_txt ts" style="border-collapse:collapse;margin-top:20px;"
 * style="padding:0px;"|Adverb{| class="ts" style="border-collapse:collapse;"
 * style="padding:0px;"|Very often; frequently.
 * }
 * }
