"Ninavua shati"

Translation: I am taking off the shirt

[Cubalibra13]

"I'm taking off my shirt" should be right, not only 'I am taking off my shirt".

[Marcus.horn25]

Neither are right. There is nothing saying that the shirt is yours (other than context). The answer is "I am taking off A/THE shirt"

I am taking off MY shirt would be "Ninavua shati yangu"

[RolandDrr]

It should be a shirt or shirt, but not a shirts?
