👉 Hirundinous is a term in Sanskrit, a language spoken in India and parts of Southeast Asia. It refers to something that is very much like a bird or insect but without wings. This term was first used by Indian poet Rabindranath Tagore in his poem "Nikunj" (1907). The word "hirundinous" comes from the Sanskrit word "hirun", which means "to fly" or "to move with the wind".
