I was pleasantly surprised to find this subforum devoted to languages! There must be a lot of language enthusiasts here at Suscipe Domine. So, what languages do you speak and/or read, what languages are you studying, and what would you like to learn in the future? I'll share my own experiences, but it might take me a while to get around to posting it all. 
My first language is British English.
I cannot speak any other fluently.
I have some knowledge of Akkadian AKA Babylonian-Assyrian. The single biggest difficulty is the (fiendishly complicated) verb system - it makes Latin verbs look childishly easy.
Would like to learn Ancient Egyptian, and Quranic Arabic. Probably never will. Biblical Hebrew ditto.
Old English is a more realistic prospect. If I could find some Old Gothic, I would give it a look.
Find Scots Gaelic fascinating
Reading Harry Potter has helped my French. The frequency with which "baguettes" are used by the pupils of "Poudlard" is apt to be confusing.
What little Italian I have is mostly derived from Dante's Commedia - so, not exactly up to date.
I think my favourite language is Greek - mostly NT - or Latin.
I have recently taken up reading Vergil in Latin - there are some very good videos on the Aeneid in Latin on YTube; to appreciate Vergil's skill as a poet, one must read him in Latin; too much evaporates when he is translated.
A friend from Brazil gave me a book on the Rosary, in Portuguese. It is simple enough for me to understood most of it.
A language I would like very much to know is German. Not to speak, so much as to read. A lot of the things I'm interested in are partly a closed book without at least a working knowledge of German.
