Grammar & word origin
durchlässig is an adjective. Its comparative forms are durchlässiger and am durchlässigsten. It comes from durch (“through”) and lassen (“to let”): the idea is that something is “let through.” The ending -ig forms an adjective. Here, lässig does not mean “casual” or “laid-back.”
