The study has contributed to compare the characteristics of the inflectional system of nouns in Arabic and English Language for pedagogical orientation. The main objective was to develop an overview of the two languages system for evaluating the pedagogical significance in Arabic and English. A qualitative research design has been implemented to introduce the nature of two languages and the anticipated difficulties that have been encountered by the learners of the Arabic and English languages. The classification of the nouns and the inflectional system of the two languages have been contrasted through the analysis. It has been observed that the Arab learners of English delete some letters while writing but have proper pronunciation because they have the habit of pronouncing two elements represented in one grapheme.
