'''[dodekalogue%|%word]''' is one of the basic syntactical units in [Tcl].  A
word is a string of characters, and a [Command%|%command] is a [list] of words.

[AMG]: The difference between speaking of a command as a list of ''words'' versus a list of ''arguments'' is whether or not the name of the command is intended to be included in the list, with ''words'' including the name.  Also note that the name of the command may comprise multiple words, as in a command [ensemble].

[PYK] 2014-04-18:   Strictly speaking, that last point, while semantically
correct, isn't syntactically accurate.  According to the [dodekalogue], the
name of the ensemble ''is'' the name of the command, and the name of the
ensemble sub-command is simply the first argument.  About the first point,
"arguments" is not a formal term in the syntax, but just a common term used to
describe the remaining words in a command after the command name.  A [list],
for example, is also a sequence of words, but contains neither a command name
nor "arguments".  [AMG], if you decide to word-smith this, feel free to delete
my comments if they no-longer apply.

A [command prefix] is an example of a list of words because it must, by definition, include part or all of the name of the command, in addition to including zero or more of the arguments to the command.

[PYK] 2014-04-18:  I can't think of any time that a command prefix only
includes part of the name of a command.  An example would be handy.  Empty
string doesn't count!

[AMG]: You answered your own question but didn't realize it.  [[[string]]] is a command prefix that only includes part of the name of a command.
