"You are a good teacher, Samia."

Translation: أَنْتِ مُعَلِّمة جَيِّدة يا سامْية.

[TheQaswarah]

Teacher = مُعَلِّمَ or مُدَرِّسَ

Please add the missing synonyms

[kara5712800]

Both of them are used in everyday speak....but You may hear أستاذ more often because it is more common than the two before especially in schools...

The word معلم is used in places like resturans/small job placs etc... i mean jobs that you learn by practicing it not by academic achievements, so here the manager/teacher/coach are called معلم ...
İn a restaurant if the waiter want to say "the manager wants sth...." You say in Arabic: "المعلم بدو" ... This is not used in MSA though

Thank you, and which of them is used more often?

[Hsn626796]

Sāmiya, or Sāmya, not Sāmiyya

[ruyalty]

And not Samiya tun either

[mishfa1]

Does not Jayyidatun mean new?

[utility_monster]

No. Jayyid is good. Jadiid is new.

[AlbertMelo5]

And this -tun at the end means both you're talking about a woman and the adjective is indefinite, i.e. a (female) good teacher

[mishfa1]

I think the correct answer should have been, "anti mu'allimatin mumtaazatun yaa Saamiya"

[MichelleDa878143]

mumtaaza means amazing
jayyida means good

[Nadjia394880]
