Estonian - as mother tongue (Estonian children do learn it at school too, that's why unlike English people we can spell in our own language quite well!
).
English - on high level (studied English philology in uni and am now studying translation, and English is the language I translate from).
Russian - on basic level (studied it all through primary and secondary school and by now I've forgotten most of what I've learnt).
Spanish - on very basic level (1 year of studying).
