The scientific term Chiroptera derives from the two Greek words χείρ chéir, "hand" and πτερόν pterón, "wing", with a clear allusion to the peculiarity of the upper limb. The two suborders have the prefixes micro- and macro- respectively to highlight the difference in size between the two groups, although the largest microchiroptera are much larger than the smallest megachiroptera. The common name bat derives from the Latin vespertīliō -ōnis, in turn derived from vesper -is, or evening, through various alterations that occurred over time such as vipistrello or vispistrello. If there is a single term in the English and Spanish languages, bat and murciélago, in other languages such as French and German, there are combinations of words to identify these animals. In the first they are known as chauves-souris, literally "hairless mice", while in the second the term is Fledermäuse or Fledertiere, or "flying mice" or "flying beasts".
