Will progress in MT require some breakthrough in grammar conceptualization? Rule-based MT requires a detailed typology of grammatical categories. But it seems that the present state of grammar conceptualization is insufficient for MT purposes. Some enhanced typology is in order. In particular the common typology relating to:

• prepositions
• conjunctions
• partitive article, i.e. the disambiguation of French ‘de’

is in need of a more accurate conceptualization.
