she lived to be ninety
what does that sentence mean?
Is it meaning of "she lived in order to be ninety" or "she lived and just became ninety"?
I have learned it as she lived and just became ninety. but I do not understand why.
infinitive used as adverb has the intention, but I have learned that is "result" so she lived and finally she became ninety years old. that is what I have learned. could you explain why it has meaning of result?
