Morphology

sleep + tight

The literal parts 'sleep' and 'tight' plausibly combine to mean 'sleep snugly' or 'sleep soundly', so a B1 learner who knows both words can often infer the general goodnight-wish sense. However, the pairing is a conventionalized collocation in English and 'tight' in this idiomatic use is not a fully predictable adverbial meaning, so the exact pragmatic formulaic usage requires exposure. Given the partial compositionality but conventionalized nature, this is best classified as semi-transparent.

Etymology

Sleep tight may come from old beds that had ropes under the mattress. People pulled the ropes tight so the bed was firm and they could sleep well. That's why sleep tight now means 'have a good night's sleep'.
