Preamble
Half-of-speech (POS) tagging is the method of marking up phrases in a textual content with their corresponding a part of speech based mostly on their definition and context. For Arabic, POS tagging is extra advanced than English due to its wealthy morphology. In Trendy Commonplace Arabic (MSA) grammar, part-of-speech hierarchy is predicated on classical Arabic grammar the place phrases are categorized into three main classes. Particle (حرف, Hurf), Verb (فعل, Fi‘l), Noun (اسم, Ism). The set of nominals embrace nouns, pronouns, adjectives and adverbs. The particles embrace prepositions, conjunctions and interrogatives, in addition to many others. This method types the core construction of Arabic grammar and the rest, is however an in depth subdivision of those important courses. These three classes are:

- Auxiliary verbs: Verbs like “كان” (to be) used to type advanced tenses (e.g., كان يكتب — “he was writing”)
3. Particles (حروف, Huruf)
Particles are phrases that don’t match into the noun or verb classes. They often function connectors or modifiers, having no unbiased that means however influencing the that means of the sentence. Particles aren’t inflected and will be brief, useful phrases.

- Emphatic particles: Phrases used for emphasis (e.g., إن — “certainly”, قد — “already”)
Hierarchy and Interactions
The three important classes (nouns, verbs, and particles) type the inspiration of the Arabic part-of-speech hierarchy. Every of those classes is additional subdivided into extra particular courses that govern their interactions. The hierarchical relationships between them will be summarized as:
Nouns can work together with:
- Adjectives to explain or qualify them (e.g., سيارة كبيرة — “a giant automobile”)
- Pronouns to switch them (e.g., ذهب أحمد إلى المدرسة → هو ذهب إلى المدرسة — “Ahmed went to high school” → “He went to high school”)
- Prepositions to type prepositional phrases (e.g., في البيت — “in the home”)
Verbs can work together with:
- Nouns to type the topic and object of sentences (e.g., كتب أحمد الرسالة — “Ahmed wrote the letter”)
- Pronouns as topics or objects (e.g., he’s writing — “يكتب”)

Noun-Adjective Settlement:
- The brand new e book (الكتاب الجديد): Right here, “الكتاب” (the e book) is a noun, and “الجديد” (new) is an adjective. In Arabic, the adjective follows the noun and agrees with it in gender, quantity, and definiteness.

Particle-Noun & Particle-Verb Relations:
- In the home ( في البيت): The preposition “في” (in) is a particle, and it governs the noun “البيت” (the home), which is within the genitive case.
- He didn’t write (لم يكتب): The unfavorable particle “لم” negates the verb “يكتب” (he writes), turning it right into a past-tense negation.
Abstract:
In MSA, part-of-speech hierarchy is primarily composed of three overarching classes—nouns, verbs, and particles—with additional subcategories and variations based mostly on their perform and relationships with one another. Understanding this hierarchy permits for the proper formation of sentences, settlement between phrases, and the flexibility to convey nuanced meanings. This structured framework is rooted in conventional Arabic grammar however remains to be relevant to Trendy Commonplace Arabic.
