The word prefix refers to an affix (unit of language composed by a letter, syllable or more than one syllable) that is added before a word to form a new word or change its meaning. As in the case of suffixes, which are added at the end of a word, prefixes alter the meaning of a word, creating new ones and most of them are derived from other languages such as Latin or Greek. In the case of the prefix "paleo-", this prefix derives from Ancient Greek language and means "ancient" or "old", for example the word "Paleontology" in which "paleo" means ancient or old and "ology" means the study of, refers to the study of animals and plants that belong to previous geological periods or animals and plants that are ancient or old. Thus, it can be concluded the prefix "paleo-" means "Ancient".
