If you're a swahili learner like me - you're probably familiar with the "hu" tense for habitual actions.

"mimi huenda kanisa jumapili"

I (usually/habitually) go to church on sunday"

I learned through my Swahili teacher when we were translating a Kenyan TV show (Selina) an alternative to this - you can add "ga" to end of verb. So the above would be:

"mimi endaga kanisa jumapili"

I'm guessing it's not grammatically correct, i've never seen this in any Swahili grammar book - seems like a more informal alternative.

I was curious if others have come across this?

Native speakers - do you also use/hear this alternative? Would you consider it grammatical or "slang"?
