 \item[(6)] If \var{s} and \var{t} are both strings, some Python
-implementations such as CPython can usally perform an inplace optimization
+implementations such as CPython can usually perform an in-place optimization
 for assignments of the form \code{\var{s}=\var{s}+\var{t}} or
 \code{\var{s}+=\var{t}}.  When applicable, this optimization makes
 quadratic run-time much less likely.  This optimization is both version
 and implementation dependent.  For performance sensitive code, it is
 preferrable to use the \method{str.join()} method which assures consistent
 linear concatenation performance across versions and implementations.
