Lithuanian 

In Lithuanian language exist not only 'dirb-dav-ome' (we used to work, and means not only repeated action (many times!) in the past, but and prolonged action which was or was not repeated many times...and to emphasise this (that we and repeated this long action many times) we repeat twice this form using 'and' - 'dirbdavome ir dirbdavome' meaning 'we used to work long works and work endlessly'), but and 'dirb-ine-dav-ome' which is the derivation from 'dirb-ine-jome' (like in Finish - to work around or to work smth but not a real work or to work anything to spend your time or to work smth insignificant).
