   A FIFO design useful in gluing the FDMDV modem and codec together in
   integrated applications.  The unittest/tfifo indicates these
-  routines are thread safe without the need for syncronisation
+  routines are thread safe without the need for synchronisation
   object, e.g. a different thread can read and write to a fifo at the
   same time.
