In general, in this context,
some serves like a plural indefinite article. Thus the use of
some does not give a definite number. But in time expressions, the OED says it means
at least a few. That is vague. And that is what
indefinite means.
The OED mentions for usage with singular nouns that some frequently implies 'not a little, considerable'. And the other dictionaries back this up. As other answers here have said or hinted, it often means: long enough! :)
A mother with a kid who is five would not say that her kid has played for some years with the next door kid who is also five. That doesn't fit.
A teenager would probably not say that she has known someone for some years now. Some does not fit the context.
As another answer has hinted or stated, the very word years means that a person has to be old enough to mean at least a few and imply a considerable amount.
In sum, the collocation some years does not at all mean a short time.
Best Answer
means to, over a period of time, think about the consequences of two or more choices in a decision. If there is only one thing you are pondering, you are pondering whether or not to do that thing.
is the same as ponder - but you can mull over collective nouns, meaning you are trying to decide which one of the group. "I mulled over the candy, and found a good piece."
means to think about the consequences of something carefully, thoroughly, and for a long time. Typically when you contemplate something, you are deciding whether or not to do it, not picking among an array of choices. It has a serious connotation, likely due to the common phrase contemplate suicide.
I don't hear this word a lot. According to Google, it can be used intransitively, so you don't have to be cogitating about anything in particular. The other words here generally require a "target" to make sense.
means the same as contemplate. When I hear this word, I think of court proceedings or meetings ("the jury will deliberate... etc.").
I don't hear this in speech very much. In my opinion it's a "less serious" version of contemplate.
means to think about something over and over. It could be the consequences of a decision not yet made, a decision that just has been made, or it could be going over past events in your mind. Dwell on can have a negative connotation, possibly that what you are dwelling on is bothering you or haunting you.
So, I would answer like this:
