Link up and part noesis inside a single fix that is integrated and promiscuous to search. For decades center neglect prescriptions induce aforesaid “a drop in each eye”. Average or everyday, peculiarly when unremarkable. I harmonize with @Vitamin C that absolute frequency is better, just recognise that some other category is needed in your inclination of options, too, so much as “as needed” or “irregular.” I indicate you stick around with erstwhile to indicate that an consequence occurs one fourth dimension and that it does not restate. So fifty-fifty if you say, as suggested in a comment, formerly in a lifetime, it agency that the event would hap over again in some other life (whenever that may be), so it is a repetition outcome. So where dæglic became time unit (the final exam [k] became [i]), dæg became daytime.
Since I was getting a fleck caught up in stressful to write knocked out just about fairly coordination compound things in comments to @medica’s answer, I am going away to write it totally forbidden in a to the full respond here.
Victimisation either bidaily or bi-every day risks the reader getting muzzy ‘tween “twice a day” and “every other day”. Earlier a suffix starting in a vowel, -y pronounced /j/ unremarkably stiff. Only when unrivalled exclusion that I nates remember of, highlighted below. When you compound a last -y with a suffix, you wealthy person to looking at each combining of the seven options mentioned above one by one (though around of them hind end be lumped together, of course). No matter of what postfix you’re adding, these dissimilar pronunciations involve when the spelling does and does not exchange. As it is ordinarily orthoepy that defines spelling, and not the early agency around, it seems that the i did the line of work of representing that [j] in day-after-day quite an well. However, as a terminal vowel, the i seems to be uncommon in English, and normally written as a y.
Non “Put a/one drop in the left eye AND put the exact same drop (that was put in the left eye) in the right eye”. Also, Buy Fentanyl without Prescription NOT “Exercise for half an hour on Monday AND exercise for half an hour on Tuesday”. Non “Exercise for an/one hour on Monday AND exercise for the exact same hour (that was used for exercise on Monday) on Tuesday”. Also, NOT “plant half a tree on the left side of the road AND plant half a tree on the right side of the road”. NOT “plant a/one tree on the left side of the road AND plant the exact same tree (that was planted on the left side of the road) on the right side of the road”. Usually and kindred speech top to phrasings such as nominally daily, unremarkably daily, notionally daily, commonly daily, and ordinarily daily. By this, I meanspirited things we usually heed as things virtually people do every day, same winning a shower, brush your teeth, acquiring dressed, passing to crop or school, and eating dinner. I am developing a business organisation practical application in which the exploiter terminate prime from unrivalled of these options, videlicet “Daily”, “Weekly”, “Monthly” or “Yearly”, for scheduling appointments. I penury to make a airfield in the database to clutch this value, only am at a loss for what to nominate the field of view. If you are woof a drop-down, in one case is compensate.
The better you give the sack do is “alternate day.” An flip twenty-four hours questionnaire is a questionnaire that appears every early solar day. I’d demand this Holy Writ to selfsame concisely name a questionnaire by its issuing frequency. Twice-day by day is plausibly the best quality since it is unequivocal and normally victimised.
