Visual guide
word + suffix sticker --------------------- dog + -s -> dogs walk + -ed -> walked house + 's -> house's ending = grammar signal
Same job, different coding no ending: dog (context) word: plural marker + dog suffix: dog + -s -> dogs many endings can encode: role, number, time, person

Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
