I understood that:
- "last but one" means: one item before the last one (e.g. "Marta lives in the last house but one" means she lives in one house before the last one)
- "next but one" means: one item next to the one (e.g. "Marta lives in the next house but one" means she lives the house after the next one)
but what if I have a graduated scale of values and I want to refer to the next and the next but one bigger values bigger than a specified value X?
E.g. I have a 10 mm hole in the whole. I wanna drill it to make it bigger. I have two tools with 20 and 30 mm diameter.
- "To make the hole 20 I have to use the next tool bigger than the hole"(?)
- "To make the whole 30 I have to use the next but one tool bigger then the hole"(?)
