Pardon the fragmentary answer, but my Italian is non-existent! ;-)

The general strategy is to use a block that alternatest the
and "to" values, then use SELECT to obtain the corresponding
value for a specific input. In this case (perhaps?) we can "cheat"
and decide only to translate the cases that are different, and
give back the input if there's no translation specified.
Thus, for example:
month-it-en: func [it-month [string!] /local en-month] [
either none? en-month: select/skip [
"GEN" "JAN" "MAG" "MAY"
] it-month 2 [
which behaves as follows:
>> month-it-en "GEN" == "JAN"
>> month-it-en "FEB" == "FEB"
>> month-it-en "MAR" == "MAR"
>> month-it-en "APR" == "APR"
>> month-it-en "MAG" == "MAY"
>> month-it-en "foo" == "foo"
You might want to use a fully-populated block of values (paired
values, actually) and let the lookup-failure value be some other
indication, such as the original value wrapped in question marks...
