Arabic Phonetic System
• Consonants (Ex: ‫ﺏ‬: b, ‫ﺖ‬: t, ‫ﻒ‬: f)
• Long Vowels (Ex: ‫ﻭ‬: w, ‫ﻱ‬: y)
• Short vowels (Ex: ُ–: u, ُ–: i) =>
Diacritics
(Buckwalter’s Arabic Transliteration System)

Arabic Morphology
Words generation is based on roots and patterns.
• Root
– Ex: k-t-b, (‘write’)
• Pattern
– faEala (main pattern = ‘do’) => kataba
– fAEil (‘doer’/agent) => kAtib: writer
– mafEwl (‘undergoer’/patient, theme) =>maktwb:
written
– MafEal (‘location’) => maktab: desk

Pronouns
• Personal pronouns
– Isolated (‘anA: I, hum: they)
– Affix-pronouns (-hu: him/it, -hunna: them.FEM)
• Demonstrative pronouns (h*A: this.MASC, tilka:
that.FEM)
• Relative Pronouns (al~a*y: who/which.MASC,
al~atAni: who/which.FEM.DUAL)

LFG for Arabic
• Objectives: induce Treebank-based LFG resources for
Arabic.
• Arabic characteristic features:
– Morphosyntactic system.
– Inflectional system (patterns, clitics, …)
– Clause types (nominal, verbal)
– Diacritics
