The Spanish word 'desechos' (meaning 'waste' or 'refuse') comes from the verb 'desechar' meaning 'to discard'. This verb can be traced back to the Latin word 'disiectare' meaning 'to throw apart', which was formed by combining two Latin elements: the prefix 'dis-' (meaning 'apart' or 'away') and the verb 'iactare' (meaning 'to throw'). The evolution from 'throwing apart' to 'discarding' and finally to 'waste' shows a natural semantic progression.

A simpler related Spanish word is the verb 'desechar', which means 'to discard' or 'to reject'. This is actually the verb form from which 'desechos' (the noun meaning 'waste') is derived. When you see 'desechar' in Spanish, you can think of it as literally meaning 'to throw away' based on its Latin origins.

While not directly related, English words that share the Latin root 'iactare' (to throw) include 'eject', 'inject', 'project', and 'reject'. All these words maintain some connection to the concept of throwing or forcing movement - 'eject' (throw out), 'inject' (throw in), 'project' (throw forward), and 'reject' (throw back). The 'ject' part in all these words comes from the same Latin source as the 'ech' in 'desechar' and 'desechos'.
