- shelf[shelf 词源字典]
- shelf: [14] Shelf appears to have been borrowed from Middle Low German schelf ‘shelf’. This may have come from the Germanic base *skelf- ‘split’, which also produced Old English scylfe ‘partition’, the word’s underlying meaning therefore being a ‘piece of split wood used for standing things on’. The derivative shelve dates from the 16th century.

- late 14c., from Middle Low German schelf "shelf, set of shelves," or from Old English cognate scylfe, which perhaps meant "shelf, ledge, floor," and scylf "peak, pinnacle," from Proto-Germanic *skelf- "split," possibly from the notion of a split piece of wood (compare Old Norse skjölf "bench"), from PIE root *(s)kel- (1) "to cut, cleave" (see scale (n.1)).
