It's important to note that Welsh has a lot of different ways to say "you" depending on the context and level of formality.
Here's a breakdown of some common ways to say "you" in Welsh:
* Ti: You (singular, informal)
* Chi: You (plural, informal)
* Tys: You (singular, formal)
* Chwi: You (plural, formal)
* Yr ydych chi: You are (formal)
So, while "i chi" literally translates to "to you" (plural), in most contexts, it's used to simply mean "you" (plural).
