[In Bengali, t]he Conditional Participle is widely used to convey "if a certain action [pertaining to the parent verb] is done,...". The logic is: "in the case or condition of a certain action being done". Being impersonal, without regard for the doer of the action that caused the condition, it is not declined to suit number or gender. If this doer is not defined in the Bengali condition clause but needs to be stated in a natural-sounding English translation, this is identified and drawn from the second clause. For example:- Student: Teaching Truth in Bengali If you pay attention,* you will learn. manoyog kar-*le* tumi shikh-be. * [or, If attention is paid] (http://www.jaspell.co.uk/bengalicourse2007/wb149study49.pdf)
