The Spanish word 'enfadado' (meaning 'angry') comes from the verb 'enfadar' ('to anger'), which was formed from Latin elements. It combines the Latin prefix 'in-' (meaning 'into, towards') with 'fatum' (meaning 'fate, destiny'). The modern form 'enfadado' includes the past participle suffix '-ado', making it function as an adjective meaning 'angry' or 'annoyed'.

The semantic development is interesting - the original concept was about something going 'into fate' or 'against fate', which evolved to express the feeling of being frustrated or angered when things don't go as planned or when fate seems to work against you.

A simpler and very common related Spanish word is the verb 'enfadar' (to anger). You'll often hear the reflexive form 'enfadarse' meaning 'to get angry'. The noun form 'enfado' meaning 'anger' or 'annoyance' is also commonly used.

While English 'fate' comes from the same Latin root 'fatum' that appears in 'enfadado', the meanings have diverged significantly. Where 'fate' retained its original meaning of 'destiny', the Spanish word developed to express the emotional reaction to fate's interference. The English word 'fatal' is another cognate that maintained a closer connection to the original Latin meaning.
