   Analysing the universal Turing machine constructed in \cite{Boolos87} more carefully
   we can strengthen this result slightly by observing that @{text m} is at most
-  2 in the output tape. This observation allows one to construct a UTM that works
+  2 in the output tape. This observation allows one to construct a universal Turing machine that works
   entirely on the left-tape by composing it with a machine that drags the tape
   two cells to the right. A corollary is that one-sided Turing machines (where the
   tape only extends to the right) are computationally as powerful as our two-sided
