According to the dictionary definitions:
having everything ordered and arranged in the right place, or liking to keep things like this.
tidy, with everything in its place.
Please let me know how the following sentences differ in meaning?
1) She likes everything neat and tidy.
2) - Your house is always very clean and tidy. How do you manage it?
- Your house is always very clean and neat. How do you manage it?
3) - My roommate is not very tidy.
- My roommate is not very neat.
I think they both mean the same thing and "tidy" is a subset of "neat". In the manner that something that is "neat" can be "tidy" too, but something that is tidy cannot always be neat. However, I cannot understand their true meanings.
