meaning - So, "in 5 minutes" means either "during 5 minutes" or "after 5 minutes" right?


Cambridge Grammar said:




We use in to say how long it takes someone to do something:


He was such a clever musician. He could learn a song in about five minutes.


We use an apostrophe -s construction (in a year’s time, in two months’ time) to say when something will happen. We don’t use it to say how long someone takes to do something:


I won’t say goodbye because we’ll be seeing each other again in three days’ time. We can also say in three days, without time, in this example.


He ran the marathon in six hours and 20 minutes.


Not: He ran the marathon in six hours and 20 minutes’ time.



In oxford dictionary,




in:- during a period of time


in 2009


in the 18th century


in spring/summer/autumn/winter


in the fall


in March


in the morning/afternoon/evening


I'm getting forgetful in my old age.


in:- after a particular length of time


to return in a few minutes/hours/days/months.



It will be ready in a week's time (= one week from now).


She learnt to drive in three weeks (= after three weeks she could drive).



so, Does Cambridge Grammar mean?


He could learn a song in about five minutes.=He could learn a song during about five minutes.?


&


we’ll be seeing each other again in three days’ time= we’ll be seeing each other again after three days?


So, "in 5 minutes" means either "during 5 minutes" or "after 5 minutes" right?



Answer



In Oxford's definition, "after a particular length of time" can be thought of as "after a particular length of time has elapsed."



So:



He will return in a few days time.



basically means:



He will return after a few days have gone by.





As for:




He could learn a song in about five minutes.



a good substitution preposition for this would be within:



He could learn a song within five minutes.



Another way we could convey this is:



It took him no longer than five minutes to learn a song.






As for during, think of that as "at some point in time during a specified interval".


Therefore:



My daughter was born in January.



means:



My daughter was born on some day in January.




And:



Hurricane Katrina happened in 2005.



means:



Hurricane Katrina happened on some day during 2005.






Bottom Line: in cases where in means during, that doesn't mean within some interval of time (such as in five minutes, or in two days), but rather for a more specific range of time (such as in the first week of the month, in December, or in the 18th century, or even in the early hours of the morning).
