Ever since the vaccination drive has started, Congress leader Rahul Gandhi on Thursday demanded free Covid-19 vaccination for all Indians. He sent out a tweet with the dictionary meaning and usage of the word 'free' to stress his point. "Free /fri?/ adjective, adverb -- costing nothing, or not needing to be paid for," he wrote, and then went on to illustrate the usage of word "free" through two examples relevant to his demands, "India must get free Covid vaccine. All citizens must receive the inoculation free of charge.”
