Peter T. Daniels (born December 11, 1951) is a scholar of writing systems, specializing in the typology of writing systems. He was co-editor (with William Bright) of the book The World's Writing Systems (1996). He was a lecturer at University of Wisconsin–Milwaukee and Chicago State University.
He received degrees in linguistics from Cornell University and the University of Chicago.
An abjad (/ˈæbdʒæd/ or abgad) is a writing system in which only consonants are represented by letter signs, leaving the vowels to be inferred by the reader (unless represented otherwise, such as by diacritics). This contrasts with alphabets that provide graphemes for both consonants and vowels. The term was introduced in 1990 by Peter T. Daniels. Other terms for the same concept include partial phonemic script, segmentally linear defective phonographic script, consonantary, consonant writing, and consonantal alphabet.
Impure abjads represent vowels with either optional diacritics, a limited number of distinct vowel graphemes, or both.
An abugida (/ˌɑːbuːˈɡiːdə, ˌæb-/ ; from Geʽez: አቡጊዳ, 'äbugīda)—sometimes also called an alphasyllabary, neosyllabary, or pseudo-alphabet—is a segmental writing system in which consonant–vowel sequences are written as units; each unit is based on a consonant letter, and vowel notation is secondary, like a diacritical mark. This contrasts with a full alphabet, in which vowels have status equal to consonants, and with an abjad, in which vowel marking is absent, partial, or optional. In less formal contexts, all three types of script may be termed "alphabets". The terms also contrast them with a syllabary, in which a single symbol denotes the combination of a consonant and a vowel.
Related concepts were introduced independently in 1948 by James Germain Février (using the term néosyllabisme) and David Diringer (using the term semisyllabary), and in 1959 by Fred Householder (introducing the term pseudo-alphabet). The Ethiopic term "abugida" was chosen as a designation for the concept in 1990 by Peter T. Daniels. Faber suggested "segmentally coded syllabically linear phonographic script"; William O. Bright used the term alphasyllabary; and Gnanadesikan and Rimzhim, Katz, & Fowler suggested aksara or āksharik.
The ancient Aramaic alphabet was used to write the Aramaic languages spoken by ancient Aramean pre-Christian peoples throughout the Fertile Crescent. It was also adopted by other peoples as their own alphabet when empires and their subjects underwent linguistic Aramaization during a language shift for governing purposes — a precursor to Arabization centuries later — including among the Assyrians and Babylonians who permanently replaced their Akkadian language and its cuneiform script with Aramaic and its script, and among Jews, but not Samaritans, who adopted the Aramaic language as their vernacular and started using the Aramaic alphabet, which they call "Square Script", even for writing Hebrew, displacing the former Paleo-Hebrew alphabet. The modern Hebrew alphabet derives from the Aramaic alphabet, in contrast to the modern Samaritan alphabet, which derives from Paleo-Hebrew.
The letters in the Aramaic alphabet all represent consonants, some of which are also used as matres lectionis to indicate long vowels. Writing systems, like the Aramaic, that indicate consonants but do not indicate most vowels other than by means of matres lectionis or added diacritical signs, have been called abjads by Peter T. Daniels to distinguish them from alphabets such as the Greek alphabet, that represent vowels more systematically. The term was coined to avoid the notion that a writing system that represents sounds must be either a syllabary or an alphabet, which would imply that a system like Aramaic must be either a syllabary, as argued by Ignace Gelb, or an incomplete or deficient alphabet, as most other writers had said before Daniels. Daniels put forward that this is a different type of writing system, intermediate between syllabaries and 'full' alphabets.

The World's Writing Systems is a reference book about the world's writing systems. The book is edited by Peter T. Daniels and William Bright and was first published by Oxford University Press in 1996.
The World's Writing Systems systematically explores most of the world's writing systems from the earliest times onwards. There are seventy-four signed articles, arranged in thirteen groups, with seventy-nine contributors (some articles have shared credit, while others merely consulted).

The modern Hebrew alphabet derives from the Aramaic alphabet, in contrast to the modern Samaritan alphabet, which derives from Paleo-Hebrew.
