Let's Speak English as a Native Speaker لنتكلم الإنجليزية مثل السكان الأصليين
Idiom : it's a bunch of words whose meaning is different from the apparent meaning of each individual word (" cleverly referring to a hidden meaning ").
إيديوم : هي عبارة عن مجموعة من الكلمات أو جملة تشير
و ترمز لمعنى أخر غير الذي يبدو لنا في الترجمة الحرفية
The picture below refers to how to say I am so happy in an idiomatic way which says ;
Walk On Air : when someone looks happy they spontaneously try to jump & fly expressing their happiness , which means they are trying walking on the air from their cheerfulness.
NOTE 📝 : idioms are mostly used by fluent English speakers to make the conversation fluid and attractive .
