What are some uses for some time in our everyday life experience? I have two interests, two interests in particular I are looking for a career in. First the person’s background which I’m interested in, and the second the relationship.

One is to refer to a period of time. In

• a week, I will spend some time to do laundry.
• She spent time running around the backyard, before returning inside.

Is “sometime” not true?

Another use is “some indeterminate point in time”. Historians

• date the fall of the Roman Empire at sometime in the late 5th century.
• I arrived tomorrow in Chicago. I expect to get the mail.

In a second usage, all online sources I’ve seen and this answer say “sometime” is correct”, and implying (as far as I can see) that some time is incorrect.

I had a feeling that “sometime” in the second usage I mentioned may not be the only acceptable form, and also that the sources I saw were British websites (though I can’t be sure). So I’ve done a Google NGram Viewer, with search terms I feel will minimise confounding results, for its frequency in BrE and AmE.

Which is the term I used for “happening some time in Happens some time in”

In American English the results show the single word version, “sometime”, to be more frequent ever since about the 60s.
Is

the two-word version of “some time” more frequent over the entire period, up to the latest point for which there is data (2008)?

“born some time in” shows the single word version leading in frequency in American English, and has been the more popular version since about the 1920s ( link ) whereas in British English the difference is much smaller, and one prevailing over the other during different time periods and subsequently not getting more used over time. Further it seems the trend is that even in British English the single word “sometime” is becoming more frequent ( link ).

I know that writers of American English will definitely say that the two-word version “some time” is definitely wrong, I’m just wondering if British English writers consider “some time” to be correct, acceptable, or incorrect, or whether they use it themselves, because there does seem to be a difference between BrE and AmE from the looks of it.

English – writing, that is, ‘to a lesser or greater extent, can be a hybrid of AmE and BrE. However, in many parts of the world it is not purely BrE like

a German does?
