Yes, I know Swedish and German, and this is the case for those words, as well. The "input" is irrelevant as long as it ends up with my thinking of the concept of "Friday" or whatever. In the case of foreign languages, foreign word goes in, "Friday" idea/color comes to mind. It's also the same if I look at a date on a calendar and see that a certain date is on a Friday, but not with the specific word "Friday". Of course, this is the same case for all the other days of the week, numbers, and the few letters. What is also interesting is if the "input" is a color very similar to the synesthetic "color/idea" for "Friday", I will also immediately think of the word/idea for "Friday" (in English). So it sort of can go back and forth.

Also, I will say that as individual letters or numbers "disappear" into a word, I do not get the synesthesia associated. So like "fourteen thousand" does not trigger the synesthesia I get for those individual digits, nor does "Amnesia" trigger my "strong" synesthesia for A, M and N. I hope this makes sense. I'm really trying to describe it as best I can.
