I always get these two verbs confused despicable and unspeakable 1)the origin of despicable derives from 'despise' 2)the origin of unspeakable derives from the verb 'speak' despise is a negative verb, is there a need to turn it into an adjective to mean the same thing again when you can use it as verb because it is self explanatory. He despises what he said or He thought it was despicable what he said. aren't these two sentences repetitive/samy? whereas speak to unspeakable is perhaps understood why one needs need to turn a positive into a negative adjective. like desire and undesirable. He spoke despicably of him. or It was unspeakbale what he said? which of these would you use mainly?
