I am trying to find some exhaustive collection of classified sample sentences - passive, with relative clauses, conditionals, and so on. Is this available? It does not have to be online, I am also OK with some published material.

  • For which language? What do you want to do with it? Are you aware of Treebanks (e.g. the Penn Treebank) and does a Treebank fulfil your needs? Commented Jul 20, 2017 at 9:42
  • @jknappen: it's for English. I want it to generate grammar drills (for EFL). I was not aware of the Penn Treebank, but it seems that's in the right direction. Commented Jul 20, 2017 at 10:36

For syntactically annotated sentences, I suggest to get a treebank, for example the Penn Treebank.

There is also a great tool called GrETEL that allows you to enter a sentence (in ordinary language) and query for syntactically similar sentences. GrETEL is supported by the European Language Research Infrastructure CLARIN.
