Payment
Brushing Off
noun, suffix
If 払う is "to pay" or "to brush off," then the noun version is payment or brushing off.
Usually 払い is tacked on the end of another word, like in カード払い (payment by credit card).
When it indicates a kind of brushing off or brushing away, it appears in words like 足払い (sweeping an opponent's legs in judo) or, more figuratively, せき払い (clearing one's throat).
The reading comes from 払う, so know that and it will pay forward your knowledge to this one.
Note that when 払い is added to the end of a compound, it becomes ばらい.
