Relating to animals with thick skin, like elephants and rhinoceroses, or describing someone who is insensitive or emotionally unresponsive.
His pachydermatous attitude made it difficult for him to empathize with others' feelings.
Pachydermatous → It is formed from "pachy-" (from Greek "pachys", meaning thick) and "derma" (from Greek "derma", meaning skin) and the suffix "-ous" (meaning full of or having the quality of). The word describes something that has thick skin or is characterized by thick skin.
Think of 'thick' ('pachy-') skin ('derma') — that's why pachydermatous refers to something with thick skin.
