<b>Structure preservingness, internal Merge, and the strict locality of triads</b>
This paper examines Emonds’ Structure Preserving Hypothesis, and suggests that the insight behind this hypothesis survives reformulation in terms of recent minimalist theory: each structure created by internal merge can also, independently, be created by external merge. As before, this makes movement (as expressed by its successor concept “internal merge”) redundant. From a meta-theoretical perspective, merge has the same formas other local relations, such as “displacement”, reflexivization and agreement. This suggests a generalization in terms of triads: linguistic relations can only affect sisters and/or their immediately dominating node. Variables can be eliminated by successive chaining of triads.
