Visual guide
word + suffix sticker --------------------- dog + -s -> dogs walk + -ed -> walked house + 's -> house's ending = grammar signal

he/him = limited case marking in pronouns
Learners from case-rich languages may expect noun endings; learners from case-poor languages may still confuse he/him.
Usually lighter in your learning language
Do not over-transfer this pattern from your own language. It is often less explicit in your learning language.
