Aedificium faciunt / construunt / aedificant.
Aaaargh . . . All the things I HAVEN'T learned about cases, declensions etc. are catching up on me now.
I am having the same problem!
Grote's Comprehensive Guide to Wheelock's Latin stresses that the cases the most important thing for understanding Latin.
Is forum really an english word?
It shouldn't be market?
Yes, it is also an English word, it's a place for discussions. I often see it in reference to Internet forums (message boards).
If it didn't accept market just report it. They accept that elsewhere if I am not mistaken.
Why are they making a building rather than constructing/building a building?
I think they want us to use the verb faciō, facere , to make.
But construō, construere and aedificiō, aedificāre would make sense, too.
why is in forum incorrect?
in foro is used for a static location. 'In the forum'.
in forum is used if there is motion into that location. 'Into the forum'.
