Can someone tell me what are the meanings of these Turkish names: "Sevil" and "Sertaç"

Thank you

Sevil means the same as where it comes from, the verb of sevilmek. It means "be someone who is loved and liked"

Sertaç means the one who is highly respected and loved.

merhaba

I like the turkish names and i want to know the meaning of this names

Nahla ,Nihal ,Filiz, Demir, Oğlu,Tuba

thanks

Nahla: There is no such name that I know of.

Nihal: Originates from Persian so it doesn´t have a common daily meaning. A names dictionary says it means loved one.

Tuba: This is spelled "Tuğba". Arabic/Quranic origin, so it doesn´t have meaning in Turkish. Means a tree in paradise.

Filiz: Sprout, a young shoot of a plant.

Demir: Iron

Oğlu: Not a name by itself but a common part of surnames, means son of.  Demiroğlu = son of Demir etc.

 teşekkür edrim

While we´re with names, can someone help me with those?

Nihat? Is this is the masculine of Nihal, or is it totally different?

Cihan?

Mersi! (as french native, had to )

Nahla is an arabic name, and it means where you can get water or food, even its verb means getting water or food

Demir is iron

Nihat is an arabic name and it means the generous

Cihan means the universe

Pas de quoi! (as french native .......

nihat is an Arabic origined name used also commonly in Turkey and means "temper".

Nihat is not the male version of Nihal. I don´t think they are related. 

Nahla is an Arabic name and I have never ever heard that it is used in Turkey. With curiosity, I searched the name on Facebook and didn´t find any Turkish users  

some store? or smth like oasis?
