I don't know how to use an adjective word to describe the same meaning of half a day. E.g. I have done all the work in the morning. In this sentence, "in the morning" means from 08:00 am to 11:59 am or what?

    I did it all this morning is a natural thing to say. It's not clear what you are asking though. Can you give us a sentence with a blank where you'd like to insert the word you're looking for?

  • Why not forenoon, which is a bit too formal, of course? " The period of time between sunrise and noon; morning" -- In fact, morning is fine, as well.

  • There is 'matutinal' which is used very rarely; the attributive noun usage (of 'morning') is common. Commented Apr 24, 2014 at 6:41

    morning is not an adjective in your example sentence.

  • @Kris: these days, I don't think forenoon is used anywhere except maybe on boats. Commented Apr 24, 2014 at 12:11

If you're looking for a term that describes the hours between midnight and noon, you can use "A.M."


morning, pre-noon - afternoon, evening, pre-midnight, post-midnight

  • Exactly what I want! Many thanks for your kindly help,DisplayName.

  • But could you please tell me the exact time for each item? Thanks! E.g. Morning=5:00-8:00? pre-noon=8:00-11:59? 12:00=noon?

Consider "matinal/matin" to refer to the early morning, i.e. the small hours before dawn.

matin/matinal: of or relating to matins or the early part of the day.

The forest, still damp from a matinal rain, was splattered all over with shifting colors of silver and soot.

Working my way up Washington Street, the only matinal activity I pass is that of the meatpackers.

  • "Matin" can also be used as a noun with a fairly horse-and-buggy flavor to it.

matin: obsolete : (early) morning. E.g. The glow worm shows the matin to be near.

We discussed that opinion which appeared in the Matin of September 17th.

In the Matin of Saturday last it was announced for the third times that bombs have been thrown by German aircrafts upon the Swiss territory.

Dlr., of Georgia, representing the Committee vu in the matin, of this bill, stated that...l

Alternatively, adjectival "antemeridional" [before noon] could work for "morning," but it has way too little currency in modern day English to be considered a valid option.
