Pulvinus is a Latin term used in French and other languages, primarily in scientific contexts such as botany and biology. It refers to a specific structure or part of an organism. In French, the word remains unchanged from its Latin form and is pronounced as /pulvi.nus/ in the International Phonetic Alphabet (IPA). It is important to be aware of the context in which the term is used, as it is primarily a scientific term and may not be familiar to non-specialists.
