Prepositions in Arabic grammar play a crucial role in constructing meaningful sentences. They help indicate the relationship between two words, usually the noun (ism) or the pronoun (ذمیر). Some common Arabic prepositions are في (in), بـ (with), من (from), إلى (to), عن (about), and على (on). Understanding and correctly using these prepositions can greatly enhance one’s fluency in Arabic.
