When it comes to expressing the idea of being aware or mindful of something, there are many options beyond the phrase "are cognizant of." Synonyms include "know," "understand," "comprehend," "realize," "grasp," "appreciate," "acknowledge," "take into account," "be mindful of," "attend to," "heed," "observe," and "perceive." Each of these words carries a slightly different connotation, making them useful in different contexts. For example, "know" might be a good choice for a straightforward statement, whereas "appreciate" could convey a deeper understanding or gratitude. By varying your language, you can add nuance and clarity to your communication.
