Please I need some help here. I am all in on learning to mimic how Japanese speak and write as well as learning proper grammar. Just knowing vocal and grammar will lead to unusual and unnatural speech, but sometimes I run into a concept that really confuses me. This sentence is an example.
I understand all the words in this sentence. I understand that it means, “I have to write a report.” My problem is my head is having trouble wrapping itself around WHY does it mean, “I have to write a report.”
When I see this sentence or sentences like it, my brain is torn in half trying to parse it properly.
Can someone please take the time to explain to me how and why this sentence and others like it communicate a requirement to do something?
Origin of ~なければ ならない is a similar question, but it doesn't really ask why which is what I am asking. Knowing it is so doesn't help me understand why it's so and how to plug into my brain how to parse it without having to stop and deconstruct the puzzle of it.
