Question: I am looking for a term to replace formulations like "the activities of the morning", "the rituals pertinent to the morning", "the morning report" (that one is from the Lion King, I couldn't resist). I tried perusing the internet search engines of my knowledge, including some searches on merriam webster's website, but I can't get a hold of what I am looking for. In fact, I will eat a better breakfast and pray every morning, now. 
Answer: I think I would use matinal, which the OED holds to have the same meaning as matutinal. However the latter they designate as now chiefly literary. The examples they provide, for matinal across three main senses, are as follows: = matutinal adj. 1. 1803 M. Charlton Wife & Mistress (ed. 2) II. i. 11 To attend the matinal dejeune's of old Gruffy in town. 1860 Ld. Lytton Lucile ii. v. 9. 30 The matinal chirp of a bird. 1862 Mrs. H.

Question: Suppose I tell something to my companion and I want to make sure he understands me. I thought I may simply ask "Do you understand me?". But recently I heard that in such cases I should ask "Does that make sense?" instead. Is this true? Which option is appropriate to use in business communication? 
Answer: I generally go with a simple: Is this explanation okay..? As it sounds neutral and encourages the receiver to provide feedback. If I used pronouns while asking for feedback, like "Did you understand..", "Did I explain this..", .. it generally makes the receiver feel like you might take their feedback negatively or take offense if they were not able to understand.

no
