GrETEL is a query engine in which linguists can use a natural language example as a starting point for searching a treebank with limited knowledge about tree representations and formal query languages.

By allowing users to search for constructions which are similar to the example they provide, it aims to bridge the gap between traditional and computational linguistics. GrETEL was developed by the Centre for Computational Linguistics at the University of Leuven.
