This particle is used to ask people's opinion/response or permission of something. You can omit the '요' if you wanna make casual sentence. ~을까요 is used for root word which ends by consonant and ~ㄹ까요 is for root word which ends by vowel.

It's used to ask alternative question when this particle is used repeatedly.

- 일본에 갈까요? 영국에 갈까요? = Should we go to Japan or UK?
- 너보고 말할까? 너보고 말하지 않을까? = Should I tell you this or not?
