I'm looking for a word that describes words that do not mean the same thing as before, for example, due to over usage.
For example, the word glitch.
a sudden, usually temporary malfunction or fault of equipment.
'Somebody help Tom, he's glitching out.'
In this case, the word 'glitch' usually refers to the malfunction of machineries, but has been used in the context of humans. It still does embodies part of its meaning in this case, but definitely not the 'equipment' part.
So, I'm wondering is there a word used to describe this behaviour of usage of the words.
