Grammar only requires a subject and an intransitive verb for completeness:

perl -e "$word{'noun'} = [qw(I you we)];$word{'verb'}=[qw(kill walk sm
+ile)]; print $word{noun}->[2] . q( ) .  $word{verb}->[1];"
[download]

Can return 'we kill' or 'I smile', both valid sentences. Transitive verbs are something like 'grace' in "I grace the scene" and requires some object to complete the sentence. That's it for grammar review.
