grammatize

"Every language," says Macaulay, "throws light on every other. We acknowledge, too, that the great body of our countrymen learn to grammatize their English by means of their Latin. This, however, proves, not the usefulness of their Latin, but ...

Grosu notes that different languages grammatize different constraints — English, for instance, has grammatized a constraint against complex prenominal modifiers, while German has not.

For example, it is sometimes suggested that German has a pair of verbal suffixes -l/-r which impart durative, or rather iterative, meaning on a verb […] Suffixation with -l/-r is thus not an instance of a productive morphosyntactic contrast, and cannot be said to grammatize durativity (or iterativity).
