I'm looking for a word that would mean " about", "around", or "approximately" while wouldn't mean "minus or plus" and just mean "or plus".
I want to say the following sentences using that word:
I will arrive there at about 8 o'clock or a little later( i.e. at 8:05 or 8:15...)
I have read about 10 books on Chinese history or a few more (i.e. maybe 11 or 12, I'm not sure).
She looks 40 years old or a little older (i.e. maybe 42-43).
My questions are:
1- Does "or so" mean "minus or plus" the given quantity, or only mean "or plus"?
2- Can I use them in all my examples? ( and how should I use them in my examples?
3- Is there any other word that would convey the meaning I mentioned and could be used in ordinary conversations?
a- I will arrive there at 10 o'clock or so./ I will arrive at 10 or so o'clock (?).
b- I have read 10 or so books on Chinese history.
c- She looks 40 or so.
d- ---( I don't know how to use "odd" in this sentence.)
e- I have read 10-odd books on Chinese history.
f- She looks 40-odd (years old).
