Mohammad,

I know your example is more a general example, but if we look at the 
specific example translating a number to a number-word we have the 
advantage that the input is an integer.

\define number-words() one two three four five six seven eight nine

<$list filter="[range[1,9]]">
   <<currentTiddler>> {{{ [<number-words>split[ ]nth<currentTiddler>] 
}}}<br>
</$list>

But this could be extended further

You could also use the number as the index to a json or dictionary tiddler.

Regards'
Tones
