Deletion of u(n)/plu
Some Glosists have insisted that u(n)/plu should be deleted after prepositions. The rule is MAY be deleted (really not a rule at all). Using u(n)/plu helps to determine the number of the noun following it. I believe the confusion came from a misunderstanding of the way Hogben deleted these words. A careful analysis of the way he deleted them shows that he deleted u(n) after prepositions and verboids, never plu . In this way, accuracy of number is preserved. Hogben never formulated this as a grammar rule. If you do not use verboids (most Glosists don't), please use u(n)/plu after the verb to separate it from the object. Do what YOU want, develop your own style of Glosa.
