do » dew
In comparison to the enormously frequent “make due” (q.v.), “make dew” is rare, and might just be a misspelling. It might even be a misspelling of the eggcorn “make due”!
(Rueful thanks to Ron Butters, who jocularly suggested this one on reading Larry Horn and me on “make due” on ADS-L, 7 May 2005.)
