This word is made up of 'der Mond' (the moon) and 'der Schein' (the glow, the light). So it literally means 'the glow of the moon'.
Der helle Mondschein erhellte den ganzen Garten.
The bright moonlight lit up the whole garden.
To express that something happens by moonlight, the preposition 'in' with the dative is almost always used: 'im Mondschein' (in the moonlight). An alternative is 'bei Mondschein' (by moonlight).
Die Kinder tanzten im Mondschein am Strand.
The children danced in the moonlight on the beach.
'Mondschein' (moonlight) is often connected with romantic or quiet activities. Typical verbs are 'spazieren gehen' (to go for a walk), 'sitzen' (to sit), or 'lesen' (to read).
Das Paar saß lange im Mondschein auf der Parkbank.
The couple sat for a long time in the moonlight on the park bench.

'der Schein' and 'der Mondschein' can both refer to light. 'Schein' is more general: it can be the light from the sun, a lamp, a candle, or a fire. 'Mondschein' is more specific and means only the light of the moon at night. The words can be confused because 'Mondschein' contains the word 'Schein'. But 'Schein' only names the type of light, while 'Mondschein' also names the source. If the light comes from the moon, 'Mondschein' is more natural and more precise.
