desinteresadamente
selflessly
adverb dehs-een-teh-reh-sah-dah-MEN-teh Rare
Also means
disinterestedly
Usage Note
Desinteresadamente derives from desinteresado (selfless, disinterested). In Spanish, desinteresado means 'without self-interest' (selfless), NOT 'bored' or 'uninterested' — those are aburrido and sin interés. This is a key false friend with English 'disinterested', which can mean impartial.
Examples
"Trabajó desinteresadamente durante años."
Natural Translation
She worked selflessly for years.
