Learn Turkish: Size yardımcı oluyorum.

In English, you say "I help you." But in Turkish, the phrases for helping (yardımcı olmak or yardım etmek) require the dative case (the "to/towards" direction). You can think of this sentence literally as "I am being helpful to you." Therefore, siz (you) becomes size (to you).

What is the -cı part of yardımcı?

The root word for "help" is yardım. The suffix -cı (which can also be -ci, -cu, or -cü) is attached to nouns to describe a person who does that thing as a role or habit. So, yardımcı literally translates to "helper" or "helpful".

How does oluyorum work here?

Oluyorum comes from the verb olmak (to be or to become). It has the present continuous suffix -uyor (am/is/are doing) and the "I" personal ending -um. Turkish frequently pairs nouns or adjectives with olmak to create verbs. Together, yardımcı olmak means "to be a helper" (to help).

Could I also say "Size yardım ediyorum"?
