What is the correct form of 'would of gotten along well'?

The phrase "would of gotten along well" contains a common grammatical error where "of" is mistakenly used instead of "have." The correct form is "would have gotten along well," which uses "have" in the conditional mood to indicate a hypothetical situation or the potential for a past event.

In this context, "would have" is used to express a conditional situation that did not happen. The verb "gotten" is the past participle of "get," making this construction appropriate for expressing a scenario in which two subjects might have formed a positive relationship.

Option B, using "good," is grammatically incorrect since "good" is an adjective and should be replaced with "well," which is the adverb form needed here. Option C changes the tense and suggests a present or future condition instead of referencing a hypothetical past scenario. Option D uses "got," which is the simple past form and is not suitable in conjunction with "would have" when indicating a conditional past.

The choice of “would have gotten along well” accurately reflects the conditional and hypothetical nature of the statement, making it the correct form.
