Language evolves. The meaning of a word can shift over time as we use it differently — think of “cool,” “heavy,” or even “literally.”
I don’t really know in English but if it is in my language, I have once. I am Thai, and I have one word that is ตา-กลม. This word is Tar-Kom. But if we separate the word to ตาก-ลม. it has different meaning. The first one mean circle eyes. The second one mean Weathering. It is a bit confusing but it is!!!
