Longum iter est per praecepta, breve et efficax per exempla.
I wanted to see if I could translate it using the book dictionary where needed. A sight translation, (given that I know of iter, per), is,
"The long road is by precept; brief and efficient by example."
Now I looked up a few things:
longus, -a, -um, adj., long
iter, itineris, n. way, road, march.
praeceptor, -oris, m, teacher, preceptor cf. magister.
praeceptum, -i, n, maxim, precept.
brevis, -o, adj. short, brief
efficio, 3, -feci, fectum, bring to pass, effect, complete; make, construct.
exempla - unknown;
assumed to be exemplum, -i, n. example
This gives me:
"The long way is by maxims, brief and complete by examples."
Now here I am wading through 3rd conjugation forms and efficax from efficio is foriegn to me now. I am sure exempla is in my L+S but it wasn't in the BLB dictionary. I am also assuming the abl. plur. for praecepta and exempla.
