Hello!

My question is: Is it possible to make „Structure Trees“ for English Sentences with „Categorial Grammar“? Sorry, I have no example.

Thanks

but there is somethin wrong, because the mistake says:

Where does that example come from? How is startlable (or maybe startlabel) defined?

there is a startlabel macro texmf-dist/metapost/mptrees/mptrees.mp of the 2017 TeXLive Supposing to compile with the TeXLive enabled, this code works: \starttext This is me \startMPcode input mptrees; u:=0.4cm; dirlabel:=90; abscoord:=true; endlabelspace:=0.5cm; draw startlabel("$S$"); draw tree[1][1]((-5.5u,4u),(5.5u,8u))("NP","","VP",""); \stopMPcode \stoptext -- luigi
