The example was recorded by E. Perekhvalskaya and V. Belikov in 1991 (Primorskij region). Nimnoshka is an adverb meaning 'a little', 'a bit'. The literal translation of the example is 'Lan is young a little'. It makes sense only if understood as comparative 'Lan is a bit younger <than me>'. In fact, Lan who was the neigbour of the speaker was a very old man.
