What does كُفُوً mean in Surah Ikhlas?

I'm referring to the last ayah of Surah Ikhlas: **وَلَمْ يَكُن لَّهُ كُفُوًا أَحَدٌ** - 112:4 What exactly does **كُفُوً** mean? Does it mean equal? Or does it mean equivalent? In the English language the terms "equal" and "equivalent" are 2 separate things. "Equal" means that two or more things are 100% same in every way. So when Allah says "*There is none equal to Him*", it implies that there is nothing that is 100% equal to him in any way. It opens up the possibility that there could be something that's "close to equal to Him". I'm guessing that it would be shirk to even believe that something is even "close to equal to Allah". Or worse, he might say that "Allah is the shape of man, but in a way that's not equal to human beings." Now you might argue that كُفُوً doesn't mean "equal". You might say that it means "equivalent". Then you have another problem. The term "equivalent" means that two or more objects are 100% same in some **specific** way. Let me give you an example: Allah and humans are equivalent in terms of seeing, but not in terms of the nature of seeing. That is because even though both humans and Allah can see, Allah still sees things in a way that's beyond human perception - He sees everything, but in a way that can't be compared to the human's nature of seeing. So if you argue that كُفُوً means "equivalent", then it opens up the possibility that Allah can have a shape that we can perceive. A person might say something like "*Allah is the shape of man, but in a way that's beyond human perception. Hence, even if Allah is the shape of man, Allah's shape and human's shape can't be compared.*" Or, he might even say "Allah is in the form of two trees, but in a way that makes Him one. It is beyond human perception". (May Allah for give me. This is just an example.) So if you're a native Arabic speaker who is very knowledgeable in the language of the Quran, please explain to me what كُفُوً really means. Because in my opinion, this term seems to be a bit ambiguous. It poses a problem whether it means "equal" or "equivalent". In both cases, one can interpret the Ayah such that Allah can have similar shapes or forms.
