but those are used in diff things
jayen vs jayiye
khaen vs khaiye
laen vs lijye
lAien vs Laiye
Khelain vs Khailye
daen vs dijye
is the one whic is more formal, i thin the latter oens are more formal than the former ones.
and ofcourse the most casual would be jao, khao, lo, lao, khelo, do etc/
right?
