Ostraca in the context of "Vase"

The Canaanite and Aramaic inscriptions, also known as Northwest Semitic inscriptions, are the primary extra-Biblical sources for understanding of the societies and histories of Phoenicia, the Israelites, and the Arameans, which includes groups within the Northwest Semitic languages. Northwest Semitic contains the Aramaic and Canaanite languages; the latter groups includes Phoenician—Punic, the Ammonite language, and Hebrew.

Semitic inscriptions may occur on stone slabs, ostraca, and ornaments and range from simple names to full texts.

Ammonite is the extinct Canaanite language of the Ammonite people mentioned in the Bible, who used to live in modern-day Jordan, and after whom its capital Amman is named. Only fragments of their language survive—chiefly the 9th century BC Amman Citadel Inscription, the 7th–6th century BC Tel Siran bronze bottle, and a few ostraca. As far as can be determined from the small corpus, it was extremely similar to Biblical Hebrew, with some possible Aramaic influence including the use of the verb ‘bd (עבד) instead of the more common Biblical Hebrew ‘śh (עשה) for 'make'. The only other notable difference with Biblical Hebrew is the sporadic retention of feminine singular -t (’šħt 'cistern', but ‘lyh 'high [fem.]'.) Ammonite also appears to have possessed largely typical correspondences of diphthongs, with words such as ywmt (יומת *yawmōt, 'days') both preserving /aw/ and showing a shift to /o/, and other words such as yn (ין 'wine') exhibiting a shift of /ay/ to ē (yēn < *yayn) much like Hebrew.

It was first described as a separate language in 1970 by Italian Orientalist Giovanni Garbini. Subsequently, a number of inscriptions previously identified as Hebrew, Phoenician, or Aramaic were reclassified, as a result of consensus around the similarity of the Amman Theatre Inscription, Amman Citadel Inscription, Tell Siren Bottle, Heshbon Ostraca, and Tell el-Mazer Ostraca.

Edomite is a Northwest Semitic Canaanite language, very similar to Biblical Hebrew, Ekronite, Ammonite, Phoenician, Amorite and Sutean, spoken by the Edomites in Idumea (modern-day southwestern Jordan and parts of Israel) in the 2nd and 1st millennium BC. It is extinct and known only from an extremely small corpus, attested in a scant number of impression seals, ostraca, and a single late 7th or early 6th century BC letter, discovered in Horvat Uza.

Like Moabite, but unlike Hebrew, it retained the feminine ending -t in the singular absolute state. In early times, it seems to have been written with a Phoenician alphabet. However, by the 6th century BC, it adopted the Aramaic alphabet. Meanwhile, Aramaic or Arabic features such as whb ("gave") and tgr/tcr ("merchant") entered the language, with whb becoming especially common in proper names. Like many other Canaanite languages, Edomite features a prefixed definite article derived from the presentative particle (for example as in h-ʔkl ‘the food’). The diphthong /aw/ contracted to /o/ between the 7th and 5th century BC, as foreign transcriptions of the divine name "Qos" indicate a transition in pronunciation from Qāws to Qôs.

The Samaria Ostraca are 102 ostraca found in 1910 in excavations in ancient Samaria (modern-day Sebastia, Nablus) led by George Andrew Reisner of the Harvard Semitic Museum. These ostraca were found in the treasury of the palace of Ahab, king of Israel, and probably date about his period, 850–750 BC. Authored by royal scribes, the ostraca primarily record food deliveries, serving an archival function.

The ostraca are written in the paleo-Hebrew alphabet, which very closely resemble those of the Siloam Inscription, but show a slight development of the cursive script. The language is typically seen as a northern Hebrew dialect.
