The present study deals with Quranic nouns which have the root (فـُعُل) (fu’ul). They have the formula of the bare triple noun. The number of words which have this formula are 19 arranged alphabetically for convenience so that the study can appear in the form of a Quranic semantic lexicon for a category of Quranic words namely:((أ ُذ ُن، اُفـُق، اُكـُل، ثـُلـُث، ثـُمُن جُرُف، حُبُك، حـُلـُم، خـُمُس، رُبُع، سُدُس، ظـُفـُر، عُمُر، عُنـُق، فـُرُط، قـُبُل، قـُدُس، نـُزُل، نـُصُب))The major finding of the study is that the classification of words which have this root by grammarians in to nouns and adjectives may only apply to part of the category. However, some words which are dealt with in this paper have both functions of nouns and adjectives with a priority of one to another.
