Comments:The meaning 'big' in Korean certainly derives from *'plentiful'. The match between Kor. khɨ- and Jpn. *kǝ̀kǝ́- appears quite satisfactory, despite the attempt of Vovin (2000) to link Kor. *hɨkɨ- with PJ *sùkùnà- 'few': it is hardly possible to analyse the Jpn. word as *'big'-does-not-exist, since all the existing compounds of this type are "noun+-na", not "adjective+-na", and anyway it is hardly possible to separate PJ *sùkùnà- 'few' (adj.) and *sùkùa-(si) 'few' (noun, adverb), see *si̯ŏ́k`ù.
