Cassar

Cassar is a Maltese surname, common both in Malta and the wider Maltese diaspora. It is considered part of the 14 most numerous surnames in Malta.

Origin
According to Maltese linguist Mario Cassar, the surname is of Arabic origin, and derives from the Muslim period of Malta. It is proposed that the meaning comes from (Arabic: قَصْر, lit. 'palace' or 'castle'). The Sicilian word, which is descendant of and has a similar meaning, is a latinisation which closely resembles "Cassar".

An alternative Arabic origin is from (Arabic: حَصَّار, lit. 'mat-maker'). The Arabic voiceless pharyngeal fricative ([], or [ḥ]) evolved into a voiceless velar plosive ([]) through spoken Sicilian Arabic in rural locations, resulting in the modern pronunciation. This 'Sicilianisation' can also be seen in other Maltese surnames of Arabic origin, and likely occurred during the 14th and 15th centuries when Maltese Muslims were forced to latinise their surnames during the Norman Occupation.

There are also various other proposed origins of the surname.:
 * It may be traced back to the Kingdom of the Two Sicilies, incorporating the island of Sicily itself, the area around Naples, and the southern part of the Italian peninsula. The surname Cassar may have derived from the given name "Cesare," and further back from the Roman family name "Caesar." In Classical antiquity, the name "Caesar" was associated by folk etymology with the Latin word "caesaries" (meaning head of hair). The Maltese Cassar coat of arms has the Latin word "SPES" (meaning "hope") inscribed on it.
 * It may also derive from a fairly common surname in Italy and Sicily: Cassara, or Cassarino, possibly from a nickname "cassaio" meaning "producer of cases". However these surnames may also be derived from the given name "Cesare" or "Caesar".
