 .SH DESCRIPTION
 .PP
 This command joins each of its arguments together with spaces after
-trimming leading and trailing white-space from each of them.  If all the
+trimming leading and trailing white-space from each of them.  If all of the
 arguments are lists, this has the same effect as concatenating them
 into a single list.
 It permits any number of arguments;
 if no \fIarg\fRs are supplied, the result is an empty string.
 .SH EXAMPLES
