Learning foreign language is a lot fun. But sometimes or even often, it can be nerve-wracking. Here goes..
When we are not conscious with what we say, we naturally go with the flow..with what is commonly used, regardless of its dictionary meaning. For non-linguist individuals, we are not aware with what is grammatically correct for as long as we end up being understood by the ones we are conversing with. But sometimes as non-native speakers of English, we have to put consciousness to our thoughts in the context of speaking to somehow avoid language barrier between two opposing point of views.
Now take a look of this sentence structure: "I eat my breakfast today." --the sentence is syntactically(deals with the rules or patterned relation that govern the way words combine to form a phrase) correct because the pronoun "I" is always followed by the base form of the verb in present tense. HOWEVER the sentence is semantically ( is devoted to the study of meaning) wrong.
To simply put it literally--"How can one eat the breakfast?". And so to make it clearly understood, it is much proper to say " I take my breakfast today". In other words, it is only a matter of choosing the right word to mean a thing correctly by replacing the word "eat" with the word "take".
Whew!kakaloka talaga ang English grammar ano?hehe!
But I hope this short lesson helps.;0)
