Among the fae summoning is considered very offensive, all depending on the individual nymph's personality they may help you if they choose to be present with you but they can be very vicious beings. The fae are free spirits they will not respond to orders they are equals to us and therefore do not wish to be bossed around.
What are your reasons ?

You can work an evocation or invocation to call such a spirit, and learn from it. However I would recommend being familiar with these practices before utilizing them.
The other option is to leave offerings in the hopes of attracting such a spirit, or to otherwise go to a location where they might reside with offerings, in the hopes of contacting one and communicating with it.
