Let's Learn Korean - Particle (으)ㄹ래요 -

This particle means 'will' or 'purpose to'. and this particle is used for verbs only.

there are 3 types of this particle:

• -을래요

           it is used for root verb which ends by consonant.


Example:  읽다                →      읽을래요          =  i will read

• -ㄹ래요

           it's used for root verb which ends by vowel.  

Example:  자다                →       잘래요            =  i will sleep

• -래요

           it's used for root verb which ends with 'ㄹ'.

Example:  팔다                →       팔래요              =  i will sell

particle (으)ㄹ래요 can't be used to the third-person subject, but we can do this with another particle, that is (으)ㄹ 거예요 (I'll put the reference link next time when I've made a post about this particle ._.v)
So, if I say this "창민이 사무실에 갈래요", in Korean this statement is wrong grammatically.
