Rashi: It is a gift [Radak ? given to a Zonah].

Radak citing Targum Yonasan: It is a wage, like an Esnan.

Malbim: Even a Zonah like this gets a fixed gift, since she is designated for one man. Why are you different ? you gave your gifts to all your lovers!

Radak: This is like Nedeh; there is a Nun in place of the Hei. Also Chazal called a dowry Nedunya.

Rashi: You did so amidst great Zenus in you.

Malbim: Aside from giving to them fixed gifts so they will love you, and bribed them to come to you from around, you adorned yourself and did strategies so they will desire you. You pursued them; they did not pursue you.
