protogenicadj.¹

Brit.

/ˌprəʊtə(ʊ)ˈdʒɛnɪk/, U.S.

/ˌproʊdəˈdʒɛnɪk/,

/ˌproʊdoʊˈdʒɛnɪk/

Origin: A borrowing from Greek, combined with an English element. Etymons: Greek πρωτογενής , -ic suffix.

Etymology: Irregularly < ancient Greek πρωτογενής first-born, primeval (see Protogenes n.) + -ic suffix. In quot. 1855 at sense 1 after German protogen (1850 in the passage translated).With sense 1 compare earlier protogeneous adj. With sense 3 compare slightly earlier protogenetic adj. 1.

1. Original, primary; of or belonging to the first or earliest stage.

Origin: Formed within English, by compounding. Etymons: proton n., -genic comb. form.

Etymology: < proto- (in proton n.) + -genic comb. form. Compare German protogen , adjective (J. N. Brönsted 1930, in Zeitschr. f. angewandte Chem. 43 231/1). Compare protophilic adj.

Chemistry.

Of a substance, molecular species, etc.: able to supply a hydrogen atom for protonation; proton-donating; = protic adj. Opposed to protophilic adj.
