+Our first task is to define an $n$-category $m$-sphere module, for $0\le m \le n-1$.
 These will be defined in terms of certain classes of marked balls, very similarly
 to the definition of $n$-category modules above.
 (This, in turn, is very similar to our definition of $n$-category.)

 duality assumptions on the lower morphisms. 
 These are required because we define the spaces of $n{+}1$-morphisms by 
 making arbitrary choices of incoming and outgoing boundaries for each $n$-ball. 
-The additional duality assumptions are needed to prove independence of our definition form these choices.
+The additional duality assumptions are needed to prove independence of our definition from these choices.
 
 Let $X$ be an $n{+}1$-ball, and let $c$ be a decoration of its boundary
 by a cell complex labeled by 0- through $n$-morphisms, as above.
