Please help me ?????

Good morning to everyone

[]

I'm writing a research paper about Synonymy in the English and [/Arabic Languages
The problem is that I can't write about the types of Arabic synonymy ?[/]
I want to know how to translate these two kinds of synonymy into english:
الترادف اللفظي
الترادف المعنوي

I hope that someone can give some advise

please I have to present my research this month[/LEFT
