IPA: /ˌɪn.dɪˈsaɪ.sɪv.li/
KK: /ɪnˈdɪsɪsɪvli/
In a way that shows uncertainty or lack of decision-making.
She spoke indecisively, unsure of what to say next.
Indecisively → It is formed from "in-" (meaning not) and "decidere" (meaning to cut off or decide) combined with the suffix "-ly" (meaning in a manner). The word "indecisively" means in a manner that is not decisive or characterized by uncertainty in decision-making.
Think of 'not' ('in-') being combined with 'deciding' ('decidere') — this helps you remember that indecisively means acting in a way that is not clear or certain.
