is a [[writing system]] that does not represent all the [[phoneme|phonemic]] distinctions of a language. For example, [[Italian language|Italian]] has seven [[vowel]]s, but the [[Italian alphabet]] has only five vowel [[letter (alphabet)|letter]]s to represent them; in general, the differences between {{IPA|/e, ɛ/}} and {{IPA|/o, ɔ/}} are simply ignored, though when stress marks are used they may distinguish them. Among the [[consonant]]s, both {{IPA|/s/}} and {{IPA|/z/}} are written {{angbr|{{lang|it|s}}}}, and both {{IPA|/ts/}} and {{IPA|/dz/}} are written {{angbr|{{lang|it|z}}}}, though not many words are distinguished by the latter. [[Stress (linguistics)|Stress]] and [[hiatus (linguistics)|hiatus]] are not reliably distinguished.<ref>{{cite book

Such imperfections are nothing new. The [[Greek alphabet]] was defective during its early history. [[Ancient Greek language|Classical Greek]] had distinctive [[vowel length]]: five short vowels, {{IPA|/i e a o u/}}, and seven long vowels, {{IPA|/iː eː ɛː aː ɔː oː uː/}}. When the [[Phoenician alphabet]] was adapted to Greek, the names of five letters were pronounced with initial vowels by the Greeks and used acrophonically to represent vowels. These were ''[[alpha (letter)|alpha]]'', ''e'' (later called ''[[epsilon (letter)|e psilon]]''), ''[[iota (letter)|iota]]'', ''o'' (later called ''[[omicron (letter)|o micron]]''), and ''u'' (later called ''[[upsilon (letter)|u psilon]]'') – {{lang|grc|α, ε, ι, ο, υ}} – five letters for twelve vowel sounds. Later the [h] dropped from the Eastern Greek dialects, and the letter ''heta'' (now pronounced ''[[eta (letter)|eta]]'') became available; it was used for {{IPA|/ɛː/}}. About the same time the Greeks created an additional letter, ''[[omega (letter)|omega]]'', probably by writing ''omicron'' with an underline, that was used for {{IPA|/ɔː/}}. [[Digraph (orthography)|Digraph]]s ''ei'' and ''ou'' were devised for {{IPA|/eː/}} and {{IPA|/oː/.}} Thus Greek entered its classical era with seven letters and two digraphs – {{lang|grc|α, ε, ι, ο, υ, η, ω, ει, ου}} – for twelve vowel sounds. Long {{IPA|/iː aː uː/}} were never distinguished from short {{IPA|/i a u/}}, even though the distinction was meaningful. Although the Greek alphabet was a good match to the consonants of the language, it was defective when it came to some vowels.<ref>{{cite book|author=Pierre Swiggers|editor=P.T. Daniels & W.

Other ancient scripts were also defective.
A famously defective
Without short vowels or [[Gemination|geminate]] consonants being written, modern Arabic {{lang|ar|نظر}} ''{{transl|ar|DIN|nẓr}}'' could represent {{lang|ar|نَظَرَ}} {{IPA|/naðˤara/}} 'he saw', {{lang|ar|نَظَّرَ}} {{IPA|/naðˤːara/}} 'he compared', {{lang|ar|نُظِرَ}} {{IPA|/nuðˤira/}} 'he was seen', {{lang|ar|نُظِّرَ}} {{IPA|/nuðˤːira/}} 'he was compared', {{lang|ar|نَظَر}} {{IPA|/naðˤar/}} 'a glance', or {{lang|ar|نِظْر}} {{IPA|/niðˤr/}} 'similar'. However, in practice there is little ambiguity, as the vowels are more easily predictable in Arabic than they are in a language like English. Moreover, the defective nature of the script has its benefits: the stable shape of the root words, despite grammatical [[inflection]], results in quicker word recognition and therefore faster reading speeds; and the lack of short vowels, the sounds which vary the most between [[Varieties of Arabic|Arabic dialects]], makes texts more widely accessible to a diverse audience.<ref>{{cite book|author=Thomas Bauer|editor=P.T. Daniels & W. Bright|title=The World's Writing Systems|year=1996|publisher=Oxford University Press|isbn=978-0-19-507993-7|chapter=Arabic Writing}}</ref>
Line 33:
However, in ''{{transl|ar|DIN|mašq}}'' and those styles of ''[[kufic]]'' writing which lack consonant pointing, the ambiguities are more serious, for here different roots are written the same. {{lang|ar|ﯨطر}} could represent the root ''{{transl|ar|DIN|nẓr}}'' 'see' as above, but also ''{{transl|ar|DIN|nṭr}}'' 'protect', ''{{transl|ar|DIN|bṭr}}'' 'pride', ''{{transl|ar|DIN|bẓr}}'' 'clitoris' or 'with flint', as well as several inflections and derivations of each of these root words.
The Arabic alphabet has been adopted by many Muslim peoples to write their languages. In them, new consonant letters have been devised for sounds lacking in Arabic (e.g. {{IPA|/p/}}, {{IPA|/g/}}, {{IPA|/tʃ/}}, and {{IPA|/ʒ/}} in [[Persian language|Persian]];<ref name="DB" />{{rp|747}} all the aspirate and retroflex stops in [[Sindhi language|Sindhi]]<ref name="DB" />{{rp|757}}). But rarely have the full set of vowels been represented in those new alphabets: [[Ottoman Turkish language|Ottoman Turkish]] had eight vowels, but used only three letters to note them.<ref name="DB" />{{rp|758}} However, four adaptions of the Arabic alphabet do unambiguously mark all vowels: that for [[Kashmiri language|Kashmiri]],<ref name="DB" />{{rp|753}} [[Kurdish language|Kurdish]], [[Uighur language|Uighur]] and [[Bosnian language|Bosnian]] languages.<ref name="DB" />{{rp|748}}
When a defective script is written with diacritics or other conventions to indicate all phonemic distinctions, the result is called ''plene'' writing.<ref>{{cite book|author=Werner Weinberg|title=The History of Hebrew Plene Spelling|year=1985|publisher=Hebrew Union College Press|isbn=978-0-87820-205-8}}</ref>
Defectiveness is a [[cline (linguistics)|cline]]: the Semitic ''[[abjad]]s'' do not indicate (all) vowels, but there are also alphabets which mark vowels but not [[tone (linguistics)|tone]] (e.g. many [[Writing systems of Africa|African languages]]), or vowel quality but not vowel length (e.g. [[Latin
