What is the past tense for akimbo?

"Akimbo" is an adverb and does not have a past tense, as it describes a position or posture (arms bent and hands on hips) rather than an action. Therefore, it doesn't change form for past, present, or future tense like verbs do. Instead, you would describe a past action that involved someone standing akimbo, such as "she stood akimbo."
