二、peak的用法

1、peak

2、peak: [16] Peak seems to come ultimately from the noun pick ‘pointed implement’ (as in toothpick). From this in the 15th century was formed an adjective picked ‘pointed’, which survived dialectally into the 19th century (S H A Hervey noted in the Wedmore Chronicle 1887 ‘Children still use ‘picked’ of a pencil with a good point to it’). It had a variant form peaked, from which peak appears to have been derived as a back-formation. The adjective peaky ‘sickly’ [19], incidentally, is not etymologically related. It comes from a now little used verb peak ‘become sickly or pale’ [16], whose origins are unknown.=> pick
