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.

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 by the Greeks with initial vowelsconsonants bymade the Greekssilent, and were then 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]]'') &ndash; {{lang|grc|α, ε, ι, ο, υ}} &ndash; 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 &ndash; {{lang|grc|α, ε, ι, ο, υ, η, ω, ει, ου}} &ndash; 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. Bright|title=The World's Writing Systems|year=1996|publisher=Oxford University Press|isbn=978-0-19-507993-7|chapter=Transmission of the Phoenician Script to the West}}</ref><ref>{{cite book|author=Leslie Threatte|editor=P.T.

Other ancient scripts were also defective. Egyptian [[hieroglyphs]] had no vowel representation at all, while the [[cuneiform script]] frequently failed to distinguish among a consonant triad like /t/, /d/ and /t'/ (emphatic /t/), or between the vowels /e/ and /i/.

A famously defective script is the [[Arabic abjad|Arabic]].<ref name="DB">{{cite book|author1=Peter T. Daniels|author2=William Bright|title=The World's Writing Systems|year=1996|publisher=Oxford University Press|isbn=978-0-19-507993-7}}</ref>{{rp|561-3}} The modern script does not normally write short vowels, but for the first few centuries of the [[Islam]]ic era, long vowels were not written and many consonant letters were ambiguous as well. The Arabic script derives from the Aramaic, and not only did the [[Aramaic language]] have fewer [[phoneme]]s than Arabic, but several originally distinct Aramaic letters had conflated (become indistinguishable in shape), so that in the early Arabic writings 28 consonants phonemes were represented by only 18 letters—and in the middle of words, only 15 were distinct. For example, medial {{angbr|{{lang|ar|ـٮـ}}}} represented {{IPA|/b, t, θ, n, j/}}, and {{angbr|{{lang|ar|ح}}}} represented {{IPA|/ǧ, ħ, x/}}. A system of [[diacritic]] marks, or ''pointing,'' was later developed to resolve the ambiguities, and over the centuries became nearly universal. However, even today unpointed texts of a style called ''{{transl|ar|DIN|mašq}}'' are found, where these consonants are not distinguished.<ref>{{cite book|author1=Richard Bell|author2=William Montgomery Watt|title=Bell's Introduction to the Qur'ān|year=1970|publisher=University Press|___location=Edinburgh|isbn=978-0-85224-171-4}}</ref>

Line 33 ⟶ 13:

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]], [[UighurUyghur language|UighurUyghur]] 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>
