Those grammars weren't all that different from yacc's grammar.
Just simpler and incomplete.

Minimal example:
A Sentence can be "Pronoun Verb." or "Verb Pronoun?"
Pronoun can be "I" or "You" etc.
Verb would be "eat" or "walk".

Sometimes you needed to 'parse' sentences in order to spell them correctly.

It is always difficult to estimate the knowledge of your (reading) public.

That is secondary school stuff (for the Dutch).
As I recall there was less to do with grammar in those foreign languages.
