What six pronouns have all ways remained the same with regard to spelling?

This is a bit of a tricky question, as the answer depends on how you define "remained the same". Here's why:

* Pronouns have evolved over time: The English language has changed a lot since its earliest forms. Pronouns have changed in their usage, grammatical roles, and sometimes even in their spelling.

* Modern vs. Old English: If we're talking about modern English compared to Old English (around 1150 AD), then almost all pronouns have changed in some way.

* Spelling changes: Even within modern English, there have been minor spelling changes over the centuries. For example, "thou" was once a common pronoun, but its spelling has shifted to "you."

However, the most likely answer to your question is:

1. I

2. you (although "thou" was more common in earlier forms)

3. he

4. she

5. it

6. they

Why these six? They have remained relatively stable in their spelling since at least the Middle English period (roughly 1150-1500). However, even these pronouns have seen minor changes in usage and grammatical roles.
