What it the meaning KITO in Japanese?

If you could put in the context of a sentence, it may be easier to know exactly what you mean but if I'm assuming correctly, it should mean 'surely or 'really' . Here's one example: kitto wakaru you ni naru yo/きっとわかるようになるよ, which means something like: You'll surely be able to understand (some day/ one day). I hope this helps!
