Etymology: From Latin Alexander, from Ancient Greek Alexandros 'he who wards of men', i.e. protector, possibly of Hittite origin; and from Alexius, from the same Ancient Greek root, alexios "helping, defending". These two origins of Alex are indistinguishable in most languages.
- (given name, male, from Greek, ), short form of Alexander, rarely an English form of Alexius.
- (given name, female, from Greek, ), short form of Alexandra or the female name Alexis, or a spelling variant of Alix.
