In Arabic pronunciation is straight forward, in english pronunciation depends on each word (a,u,o) can have a different sounds (depends in which word used) and the emphasis also is a dark magic :D there are no such exceptions in Arabic
Arabic can be difficult but simple. English can be easy but complex.
As he pointed, you might tell your girlfriend this is a gift from your dog (كلب) instead of heart (قلب), but I'm sure that if she is a native speaker, she'll understand correctly.
I've seen the same mistakes happen in other languages, but the native speaker usually miss the meaning.
I think this relates to the fact that Arabic spoken language has a vast number is unique dialects, and they mostly understand each others dialects, unlike other languages that differs between dialects mostly in spelling sounds.
It is also highly regional. Someone from Glasgow pronounces things rather differently to someone from Brighton.
I don't speak Arabic, but my understanding is that someone from Morocco can't necessarily hold an easy conversation with someone from Qatar.
Whereas, I can name very few varieties of English that aren't easily mutually intelligible with basically all of the rest of the English-speaking world - patois and gullah, for example.
"I read that magazine": do I mean regularly, or that I have done in the past?
"The messenger wrote down Lincoln's address": was that his home, or his speech?
The context would need to be quite explicit to work around problems such as this.
“Dog” and “cat” have different pronunciations in English, and therefore mean different things.
There are many word pairs in many languages that are written exactly the same way but have different pronunciations and different meanings.
The verb "lead" and the noun "lead" (i.e., the metal) are two different words, pronounced differently. The fact that they are spelled the same is just an example of how the English writing system doesn't encode the English language perfectly accurately.
