Morphology

sleeplike = sleep (transparent) = sleep + like

The adjective is directly formed from 'sleep' + the productive suffix '-like' meaning 'resembling'.

Etymology

The word sleeplike joins sleep and the ending -like, which means 'similar to'. So, something sleeplike looks or acts 'like sleep', which helps you remember it means 'resembling a sleeping state'.
