The second feminine plural pattern is فُعَلٌ, a broken plural. Rather than adding -āt, it changes the internal template.
كُبْرَى ← كُبَرٌ — a formal plural pattern related to greater feminine entities.
صُغْرَى ← صُغَرٌ — a formal plural pattern related to smaller feminine entities.
The two entries فُعْلَيَاتٌ and فُعَلٌ must be kept separate. They differ morphologically, and actual lexical usage does not necessarily employ both alternatives equally for every root.
