The use of "the" for both properties and some (but not all) functions is
among the few mistakes the original HyerTalk team made.
If "the" were used exclusively for properties, there would be no
confusing ambiguity.
Worse, using it for functions only works with a subset of functions
where the number of params is 0 or 1, but not two or more.
And while we can use "the" with a subset of built-in functions, we can't
with custom functions.
Lots of "sometimes" rules were introduced as by-products of that design
decision, making the learning curve more steep even as it attempts to
lower it.
LiveCode has little choice but to follow the established convention,
butt when I teach newcomers I never even show them that "the" can
sometimes be used for functions.

HyperTalk was once arguably "English-like" back when the alternatives
were C and Pascal. When it premiered there were very few scripting
languages; among the few in widespread use was bash, which is wonderful
but sparse, and thus not very readable.
Today, scripting languages have followed Osterhout's prediction from the
'90s to become a leading means of developing applications.
One of the key goals of any scripting language is to provide readable
code. Ruby, and maybe more so Lua, are nearly on par with LiveCode for
readability when we compare professionally-written production code.
E.g. this:
put arrayEncode( the customProperties["Prefs"] of stack "Prefs" ) \
into url ("binfile:"& specialFolderPath("Preferences") & \
"/MyPrefs.dat" )
...is readable enough, but far from English.
What LiveCode brings to the modern world is a high-level scripting
language distinguished not by any conformance to the rules of English,
but by being among the very few that include support for GUI controls as
inherent language elements.
With LiveCode, that occurs across a platform coverage that I don't
believe any other scripting language with integrated GUI support offers.
