my $rx = qr/
^ # At the beginning of the string
( # Capture in $1
(?: # Paren for grouping (don't capture in $2)
\w # match a "wordy" character
(?: # paren for grouping,
\s+|\z # match at least one space or the end of the
)* # zero or more times
) # end of capture $1
(.*) # and match what comes after storing it in $
/x # allow these comments
The rationale is to match at the beginning all the one-character strings, storing them in $1. The rest of the input will be catched in $2
