| | Some interesting attributes on morphologic layer are ''form'', ''lemma'' and ''tag''. Some interesting attributes on analytical layer are ''afun'' (analytical function) and ''ord'' (surface word order). To reach ''form'', ''lemma'' or ''tag'' from analytical layer, that is, when calling this attribute on an ''a-node'', you use ''$a_node->get_attr('m/form')'' and the same way for ''lemma'' and ''tag''. The easiest way to see the node attributes is to click on the node in TrEd: |

Mostly, these do not differ. | //Note//: ''get_children()'' returns topological node children in a tree, while ''get_eff_children()'' returns node children in a linguistic sense.
