тавонистан: to be able
Сan you swim? Yes I can. (Are you able to swim. Yes, I am able.)
Ман метавонам ба шумо пул диҳам.
I can give you money. (I am able to give you money.)
The second sample sentence could also be written like this:
Ман ба шумо пул дода метавонам.
Colloquially, the letters ав are often dropped. So the first example would be:
Шумо шино карда метонед? Ҳа метонам.
From the same root, тавоно is an adjective that means “able”, and is sometimes translated as “powerful” or “capable”.
