The Spanish word 'desdichado' (meaning 'unfortunate') has an interesting etymology that starts with the Latin word 'dicta', meaning 'things said'. This evolved into the Spanish word 'dicha', which took on the meaning of 'happiness' or 'fortune'. The addition of the negative prefix 'des-' created 'desdicha' (misfortune), and finally, adding the participial suffix '-ado' formed 'desdichado' (unfortunate).

This evolution shows how a word referring to 'things said' came to mean 'fortune' (perhaps through the concept of declaring or speaking of good things), and then how adding negative and participial elements transformed it into a word describing someone affected by misfortune.

Some related Spanish words that might be more familiar to Spanish learners include 'dicha' (happiness), which is the positive base word. You might also encounter 'desdicha' (misfortune) without the participial ending. The prefix 'des-' is very common in Spanish and appears in many basic words like 'deshacer' (to undo) and 'desaparecer' (to disappear), following the same pattern of negating the base word.

While there aren't direct English cognates of 'desdichado', English words that share the Latin root 'dicta' include 'dictate', 'dictation', 'dictionary', and 'predict'. All these words relate to speaking or saying something, preserving the original meaning of the Latin root, while the Spanish word evolved to relate to fortune or fate.
