Why then is "tunahuzunika" not accepted as a correct answer?
I thought "we are grieving" is in present tense?
Verbs that express states of being use “me” in the present tense. Example: nimefurahi: I am happy VS
Ninafurahi: I am BECOMING happy. Your confusion may be because “grieving” is an emotion but it’s written as a verb in English.
Tunahuzunika refers to entering a state of grieving, not being in the state of grieving.
