It still is a route, as in, an entry
in the local computer's routing table.
In IP, routing means connecting to other networks. In fact, that was
the original purpose of the Internet. Way back in the dark ages, there
were a lot of different network types, such as Ethernet, token ring,
ARCNet, DECNet, SNA, IPX and more. They couldn't talk to each other.
The goal of the Internet was to provide some means to tie them
together. So, right from the start, if you were using IP, then you were
very likely connecting between networks. Conversely, routing is not used
when connecting among devices on the local LAN. If you can read the MAC
address for another device, you're not routing.
