coi mi'e kris.

.i mi masno cilre la lojban.

.ini'o mi nelci le la djan. le lisri
.iku'i mi na jimpe pa cmalu:

>.i kurji catlu mu'i le nu noda zgana

It looks to me like this would mean "She looked around carefully
because no one was watching". I am guessing what is meant is "She
looked around carefully to make sure no one was watching"
I thought "mu'a" meant "because".  Where am I going wrong with this?

to .u'uzo'o mi pu nitcu le malglibau
