First off, I apologies for the redundancy of this question. I am aware that there are already several questions dedicated to the use of colons and/or semicolons. However, non of the questions I saw seemed to address sentences with grammatical structure similar to my own and I was unable to determine what punctuation I should use. Should I use a colon, semicolon, or some other punctuation? (I will indicate with a question mark the location of the punctuation in question.)
- Far from an encumbrance, he regarded her aspirations as an occasion to mold himself to the cherished contours of her heart ? to let her rupture his soul into metamorphosis.
- It was the only way he knew to requite the scandalous honor she had bestowed upon him in her obstinate determination to wed him ? an unprecedented impropriety that had incensed her family, but one which would always wreathe his memory in pleasure.
In neither example do I feel confident that the resulting halves as divided by ? are independent clauses or complete sentences (a requisite for semicolons, I believe). At least, I do not believe that starting from and following to let her rupture & an unprecedented impropriety are stand alone sentences (given the manner in which they begin). So I am hesitant to use a semicolon. However, I am not sure that either of these examples are congruent with any of the grammatical structures outlined in other questions as warranting the employment of a colon. Irregardless, I feel that a mere comma would be insufficient.
