 ### Dart2JS
 
-- Adds support for deferred loading of types seperately from classes. This
+- Adds support for deferred loading of types separately from classes. This
   enables dart2js to make better optimization choices when deferred loading.
   This work is necessary to address unsoundness in the deferred loading
   algorithm. Currently, fixing this unsoundness would result in code bloat, but
-  loading types seperately from classes will allow us to fix the unsoundness
+  loading types separately from classes will allow us to fix the unsoundness
   with only a minimal regression. To explicitly disable deferred loading of
   types, pass `--no-defer-class-types`. See the original post on the
   [unsoundness in the deferred loading algorithm][].
