The “Syntactic relations” allows you to use the type of syntactic relation between the words as a search condition.

The syntactic relation has a direction - it goes from “parent” to “child”, from "head" to "tail". For example, in the phrase red ball, the noun ball is a parent or a head, and the adjective red is a child or a tail. They are linked by modificative syntactic relation.

In the syntactic structure of a sentence, each word has exactly one syntactic relation where it is a tail. The number of syntactic relations where the given word is a head, is not limited. It may be 0 as well. Thus, the syntactic structure is a rooted tree in the mathematical sense. Word forms are the vertices of the graph, and syntactic relations are the edges. Although for any pair of words in a sentence there is a “path” of syntactic relations connecting them, they can be directly connected by only one relation.

To specify a syntactic relation, you need to select its type and the position of the word in question - whether it is a head or a tail.

In a query, you can specify more than one type of relation using the disjunction sign | (logical "OR"). Since a syntactic relation is specified for a pair of words, and no more than one relation can link them, the logical “AND” is not applicable here. If the field is active, but relation type is not set, relations of all types will be retrieved. Relation types can be selected using the menu, opened by the “Select” button, or they can be typed. For an inventory of syntactic relations and necessary comments, see the corresponding section of User's Guide.
