shelf是什么意思_shelf怎么读_中英文释义(含例句用法)

shelf: 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.
shelf (n.): 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)).

Shelf life first recorded 1927. Phrase on the shelf "out of the way, inactive" is attested from 1570s; of unmarried women with no prospects from 1839. Off the shelf "ready-made" is from 1936. Meaning "ledge of rock" is from 1809, perhaps from or influenced by shelf (n.2). Related: Shelves.
shelf (n.2): "sandbank," 1540s, of unknown origin. Related: Shelfy "abounding in sandbanks."
