OK, let me make this a formal suggestion for an item.

The things called 'predicates' in the M&S shall henceforth be called 
'properties' (preferred) or 'relations'.
This is in line with the standard usage in the description logic, 
database and formal logic communities, and is used in the DAML+OIL 
documentation. The term 'predicate' is deprecated as potentially 
misleading, since properties are not predicates in the sense that 
word is usually used in formal logic.
