Correct spelling for the English word "reekless" is [ɹˈiːkləs], [ɹˈiːkləs], [ɹ_ˈiː_k_l_ə_s] (IPA phonetic alphabet).
The word "reekless" can have two possible etymologies:
1. Reek + -less: In this case, "reekin" is derived from the Middle English word "reken" which means "to emit smoke, steam, or strong odor". The suffix "-less" is added to indicate the absence or lack of something. Therefore, "reekless" would mean "without reek" or "not emitting a strong odor".
2. Wreak + -less: An alternative explanation is that "reekless" is a combination of "wreak" and "-less". "Wreak" comes from the Old English word "wrecan" which means "to cause, to inflict", often used in the context of causing damage or harm. The suffix "-less" is then added to indicate the absence or lack of something.
