I have to insert a wire into another wire, they said that the thinner wire goes (as far as) to the extent that it will go.
I am having trouble interpreting this.
Does it mean there's no limit for the wire to go, or it means there's a limit and it shall reach such limit?
Replace the phrase as far as by to the extent that, and you get the meaning. It means; the wire fixes its limit; you go on pushing the wire as far as it goes inside, the moment it stops, that is the end of it and that is the limit.
