On a recent phone call, the person I was talking to ended nearly every inquiry with “Perfect,” even if it had no application to our topic of discussion. I eventually realized she was using this as a filler word, also called discourse marker, to fill in the silence that accompanies speech between humans. People used to commonly use “awesome.” Others over the years have included the British “brilliant,” the old-fashioned “groovy,” the hipster “right on,” and a slew of others, including “um,” “ah,” and “like.”
Interesting comments. I do not like filter words in writing.
