if we need to view/extract later the words that have at least 7 characters we can:

str_view( stringr::words, "........*", match = T)

adding "*" after the eight "." states that the last "." can be repeated zero or more times.

or

str_view(stringr::words, ".{7,}", match = T)

in both cases we match the words that have at least 7 characters, not only up to the seventh letter
