The word literally is vastly used in English as.. a filler word.
Which means that sometimes people use it in addition to a perfectly structured sentence not because of its literal meaning but for the sake of sounding more ‘natural’, filling in the gaps and buying time to come up with the rest of the sentence.
I’m not a filler word hater like many of my colleagues in the public speaking industry.
As non-native speakers, we sometimes need the additional split second to retrieve a missing word. The fact is that everyone uses it to a certain degree. It’s all a matter of moderation.
