Tongue and Groove

• Tongue and groove or TG is a method of fitting
  similar objects together, edge to edge, used
  mainly with wood flooring, parquetry, panelling,

  joints allow two flat pieces to be joined
  strongly together to make a single flat surface.
• The effect of wood shrinkage is concealed when
  the joint is beaded or otherwise moulded
