Dear Ragoda
u have to say i'm so embarrassed , usually when we talk about an adjective that modifies ourselves or people (
(human being )
we put ED at the end of the verb to make an adjective that is a modifier for human
but we usually put ING if we describe things
Example
i'm so embarrassed >>انا محرجه
this is an embarrassing situation >>موقف يسبب الاحراج
..................
i'm so tired
this work is tiring
...................
he is exhausted
this job is exhausting
........................
i'm amazed
this is amazing
Got it ??? Good luck dear
