Noun. Shortened version of "tomorrow
morning," but its use is also similar to that of tonight. Can also be used in the sense of "this
morning," although such use is less
common. See also tomorn, tomornin and tomornin'.
Anytime the day before, from after noon until midnight (or later, depending on location and preference), you may say, "What are you doing tomorning?" --What are you doing tomorrow morning?-- or "
Hey, can I catch a ride to work with you tomorning?" --Hey, can I catch a ride to work with you tomorrow morning?--
During the wee hours of the morning, you can say, "I am going to
school tomorning." --I am going to
school (later) this morning.-- However, this is not a commonly used form of the word.
