His/pp$ father/nn Soeren/np was/bedz the/at village/nn apothecary/nn whose/wp$ slender/jj income/nn made/vbd it/ppo difficult/jj to/to feed/vb his/pp$ family/nn ,/, let/vb alone/rb educate/vb them/ppo in/in a/at town/nn without/in even/rb a/at school/nn ./.
The/at two/cd older/jjr boys/nns ,/, Hans/np and/cc Anders/np ,/, his/pp$ junior/jj by/in a/at year/nn ,/, therefore/rb went/vbd daily/rb to/in the/at home/nn of/in a/at warm/jj and/cc friendly/jj wigmaker/nn nearby/rb for/in instruction/nn in/in German/np ;/. ;/.
his/pp$ wife/nn taught/vbd the/at two/cd boys/nns to/to read/vb and/cc write/vb Danish/jj ./.
