Consider the sentence “I will finish it tomorrow”. Now if you want to emphasize the time you will say “I will finish it tomorrow itself”.
Consider the sentence “He told me that he got a lottery”. Now to emphasize who told you, you will say “He himself told me he got lottery”.
Sometimes Indians tend to create such sentences as “He only told me”, “You only asked me close door” etc.

In Marathi, we use च(ch) to emphasize on the word. च(ch) is a one-size-fits-all kind of suffix. You can add it कर्ता (kartA) i.e. doer of the action, कर्म (karm) noun, verb or any other word which you want to emphasize.

Let us see examples

I myself did it -> मीच हे केले (mIch he kele)
I did this itself -> मी हेच केले (mI hech kele)

I will come tomorrow itself -> मी उद्याच येईन (mI udyAch yeIn)
I will surely come -> मी येईनच (mI yeInach)

I have seen India only -> मी भारतच बघितला आहे (mI bhAratach baghitalA Ahe)
Is this the result of my efforts? -> माझ्या मेहनतीचा हाच परिणाम का (mAjhyA mehanatIchA hAch pariNAm kA)

He kept on talking -> तो बोलतच राहिला (to bolatach rAhilA)
He kept on staring that car ->तो ती गाडी बघतच राहिला (to tI gADI baghatach rAhilA)

I want only sedan car -> मला सिडान कारच पाहिजे (malA siDAn kArach pAhije )

I must go there -> मला तिथे जायलाच पाहिजे (malA tithe jAyalAch pAhije )

Why just me? -> मीच का (mIch kA)
