-ic

• -ick (obsolete)

From Middle English -ik, from Old French -ique, from Latin -icus, from Proto-Indo-European *-kos, *-ḱos, formed with the i-stem suffix *-i- and the adjectival suffix *-kos, *-ḱos. Compare Ancient Greek -ικός (-ikós), Sanskrit -इक (-ika) and Old Church Slavonic -ъкъ (-ŭkŭ). Doublet of -ac and -y.

PIE *-kos on noun stems carried the meaning 'characteristic of, like, typical, pertaining to', and on adjectival stems it acted emphatically.
