English.
oh, were you hoping I'd put something else? yeeeeeeeeeeeeeeahno... i'm not that slick.
ok, well, if you insist, i took a year of German and a year and a half of Spanish in high school, and I still remember stuff like Radiergummi and Papierkorb, miel and pepino. I can plow my way through
reading Spanish, but I couldn't
construct a sentence to save my life, and I'm not very good at picking out individual words when I hear someone speaking it. Because I can read Spanish, I can often puzzle out the basic meaning of stuff in French.
I also know something in the neighborhood of 100 words in Swahili (jambo... jambo bwana... habari gani?) although I often forget them and have to refresh when I want to use them, 15ish words in Tagalog (issa, dalawa, tatlo...) , and assorted random phrases in Telugu (toilet akkado meeku telusa?!) and several lines from a poem in Sindarin (ai! laurie lantar lassi surinen!).
But, honestly, if you wanted me to hold up my end of a conversation, write a letter, or get information... it really would have to be in English.
