pulchritudinous, adjective: ‘beautiful; physical comeliness’. /ˌpʌlkrɪˈtʃuːdɪnəs/
Example: ‘He gazed admirably at the pulchritudinous brunette.’
Origin: Middle English; Latin pulchritūdō “beauty” (from Latin adjective pulchr-, pulcher “beautiful”) + adjectival suffix -ous “full of”; the verb pulchrify “beautify”, the noun pulchritude “beauty”, and the adjective pulchrous “fair or beautiful” are other pulcher offspring, however, fleeting ones (i.e., they are archaic and not used frequently in Present-Day English).
