Tricky Words in this week's OVI
Words ending in -ly. Most English words ending in -ly are adverbs (príslovky), and they express how, where or when, in what way or manner, or to what degree, something exists. In this week's extracts there are three: naturally, specifically and socially. Interestingly (that's another one), all three look as if they end in double-ly, but that's only because the basic form of the root adjective ends in -l (natural, social), except for specific, which changes to specifical before getting the -ly ending (like economical - úsporné).
If you've also found the word "costly", award yourself a little beaver badge for observation, but note that this is an adjective (prídavné meno), "nákladné" in Slovak, and it belongs in the group with likely (pravdepodobné), lovely (rozkošné), friendly (priateľské), lively (živé, as in "živé detsko"), manly (mužské), timely (včasné), daily (každodenné) and deadly (smrteľné, smrtiace).

Thanksgiving. This very important family holiday in the USA was established by Abraham Lincoln for all states in 1863, to encourage unity during the Civil War, and Franklin D. Roosevelt set the fourth Thursday in November (not always the last) as Thanksgiving Day in 1942. Thanks were originally given for a successful end to the harvest (žatva) season, and the most important harvest is generally considered to have been the one which saved the colony of Pilgrims (pútnici - Protestant refugees from England) at Plymouth, Massachusetts in 1621, with the help of Native Americans.
The traditional Thanksgiving dinner consists of roast turkey (moriak) and all the trimmings (obloženie) followed by puddings (nákyp) and cakes. Thanksgiving is also celebrated in Canada, but on the second Monday in October, because the harvest ends earlier further north.
