According to Script:
Vocabulary Advice

Cal Simone

One of the beautiful things about AppleScript is that it allows you to do nearly anything
you want in your vocabulary; however, just because it allows something doesn't mean
that you should do it. To help guide you, I'll regularly include miscellaneous pieces of
vocabulary advice in this column. This time I'll address words to avoid in your
vocabulary. Here are a few examples:

Let's look more closely at the problem with using end. Keep in mind that users are
accustomed to seeing end at the end of a block, and AppleScript automatically appends
the word tell, repeat, if, or the name of the handler after the  word end if the user
types end on a line by itself. For example:

if the moon is blue
...
end [if] -- AppleScript fills in the "if"

 

If you use end as part of a verb name in your vocabulary, such as end animation,
users will type the word end by itself and expect AppleScript to fill it in. Of course,
this won't happen for a dictionary-defined command like end animation, which isn't
a true block construct, so it will appear that the AppleScript compiler is behaving
arbitrarily.

begin animation
...
end -- AppleScript doesn't fill in "animation"

 

This confusion already exists in the case of the Database suite event End Transaction. In
dictionaries of applications that support transactions, users find themselves having to
remove the word transaction in the phrase end transaction whenever they
recompile a script. Don't create this confusion in your vocabulary -- it's better to use
verb names like start animation and stop animation. Users will assume that the
full verb name is required.

start animation
...
stop animation
