Brit.

/pɪkˈnɒtɪk/, U.S.

/pɪkˈnɑdɪk/

Forms: 1900s– pycnotic, 1900s– pyknotic.

Origin: A borrowing from Greek, combined with English elements; modelled on a German lexical item. Etymons: Greek πύκνωσις , -otic suffix, pyknosis n.

Etymology: In sense 1 < ancient Greek πύκνωσις condensation, condensed matter (see pyknosis n.; see -otic suffix), after German pyknotisch (1899 in the passage translated in quot. 1900). In sense 2 < pyknosis n. (see -otic suffix). Compare Hellenistic Greek πυκνωτικός serving to close the pores, (of winds) bracing.

1. Designating a theory according to which the matter in the universe was formed by condensation of a universal substance or ether at particular points; of or relating to this theory. Now historical and rare.

1900 J. McCabe tr. E. Haeckel Riddle of Universe 222 In fundamental opposition to the theory of vibration, or the kinetic theory of substance, we have the modern ‘theory of condensation’, or the pyknotic theory of substance [Ger. die pyknotische Substanz-Theorie]. It is most ably established in the suggestive work of J. C. Vogt.

1904 Contemp. Rev. Apr. 504 The pyknotic theory of substance differs from the kinetic theory..in so far as the centres of condensation of the primitive ether are endowed with sensation and will.

1920 T. Dreiser Hey Rub-A-Dub-Dub xii. 163 This squares with the first or pyknotic law of energy, as laid down by Vogt.

2005 Ş. Hanioǧlu in E. Özdalga Late Ottoman Society ii. 74 Die Welträthsel, perhaps the masterpiece of pyknotic Monism.

2. Cell Biology. Of, relating to, or displaying pyknosis.
