all characters using Life Modules
must purchase the following (at a cost of 850 XPs): +100 XP to each
Attribute, Language/Affiliation Primary or Secondary Language
Skill (+20 XP), Language/English Skill (+20 XP) and Perception
Skill (+10 XP).
so if you look at house Davion
primary language is English
secondary languages are: French, German, Hindi, and Russian
IF you choose the Capellan March, as your sub affiliation, you also get 5xp into Cantonese, German, Mandarin, Spanish, or Russian
so ANY of those languages could get the 10 point reduction.
I look at something like that -10xp to language, as for a practical example, in High school I basically had to take 1 class of non English language, the only one offered at the time was Spanish, which I took, did not necessarily apply myself very hard and essentially never used it since, which means I lost 90%+ of it, so for all practical purposes, I may recognize Spanish, (and Spanish descended languages) but I won't understand what's actually being said, and most likely will not be able to make myself really understood.
