Famousness comes from 'famous' + the noun-forming suffix '-ness'. 'Famous' is from Old French 'fameus', from Latin 'fāmōsus' ('much talked of'), from 'fāma' ('report, rumor, fame'), from Proto-Indo-European '*bʰeh₂-' ('to speak'). Morphologically, the form is compositional, with the named elements combining to produce the modern spelling and sense. In present use, it is used as a noun meaning "the state of being widely known or celebrated", so the historical material remains connected with the current sense rather than standing as bare ancestry. The wider English family includes related forms such as famous, fame, and famously, showing how the same historical material continues to organize neighboring vocabulary. The named historical forms include Latin fāma and Proto-Indo-European *bʰeh₂-, keeping the history tied to concrete forms rather than a loose resemblance.
