Sandra

Sandra is a feminine form of the name Alexander, which is derived from the Greek name Alexandros. Alexandros is composed of the elements 'alexein' meaning 'to defend' and 'andros' meaning 'man,' thus giving the name the meaning 'defender of men.'

The name Alexander has been popular throughout history, particularly due to its association with Alexander the Great, the famous Macedonian king and military commander from the 4th century BCE. The feminine form Sandra emerged as a separate name in various cultures and languages, including Spanish, Italian, and English.

While Sandra does not have a specific meaning beyond its connection to Alexander, it has developed a strong and independent image as a feminine name. It's a popular name in many countries and has been particularly common in English-speaking regions since the mid-20th century.

Overall, Sandra is a classic feminine name with Greek roots, carrying a sense of strength and protection inherited from its masculine counterpart, Alexander.
