Bird

Origin: The word צִפּוֹר (tsipor) originates from Biblical Hebrew. Its earliest known form is צִפּוֹרָה (tsiporah), related to the root צ-פ-ר (ts-p-r), which means 'to chirp' or 'to twitter'. The form evolved into צִפּוֹר in post-Biblical Hebrew.
Historical and Cultural Context: In the Biblical texts, צִפּוֹרָה is used to describe various small flying creatures. It is also famously the name of Moses' wife, Tzipporah, which signifies a 'bird' or 'beauty'.
Evolution: Over time, the term צִפּוֹר was generalized to refer to birds in general rather than specific species. Cognates of the root can be found in other Semitic languages, like Arabic صُفُور (ṣufūr), which similarly refers to birds.
Modern Relevance: Today, צִפּוֹר is used in Modern Hebrew to refer to birds generally. It features in various idiomatic expressions, such as 'ציפור הנפש' (tsipor hanefesh) meaning 'a person's innermost feelings or soul'.

The Hebrew word צִפּוֹר (tsipor) not only signifies 'bird' but also appears in Jewish folklore and Kabbalistic texts as a symbol of the soul's flight.
