The word مُعَلِّمَة (mu3allimah) is a noun, which means a teacher, and مُعَلَّمَة (mu3allamah) is an adjective, which means taught or marked.
The only difference is the small diagonal line below the first word and above the second one. Notice that the letter ل (L) has another mark above it (like a small w). It's called shaddah, and it's the reason why you see doubled letters in Arabic romanization.
The mark above the second ـمـ (m) doesn't matter, because it's written and pronounced the same way either way.
Hmmm... I see where the issue is.... I'm trying to paste "مُعَلِّمَة" (mu3allima), but for any reason, it switches to "mu3allama". Well... here you can see how to write it well: https://en.wiktionary.org/wiki/%D9%85%D8%B9%D9%84%D9%85%D8%A9#Arabic Anyway, if I'm not wrong, arabic drops all these small vowels and the little circle (for consonants with no vowels).
