Enow is a somewhat uncommon spelling of the word "enough", which means "sufficient" or "adequate". The IPA phonetic transcription for this word is /ɪˈnaʊ/, which represents the pronunciation of the two syllables "i" and "naow". The spelling "enow" is not often used in modern English, but it can be found in older literature and poetry. In general, it is better to use the more common spelling "enough" in writing and conversation to avoid confusion.

The word "enow" is derived from Middle English "enough" and Old English "genōg", meaning "sufficient" or "adequate". The "g" in Old English gradually shifted to a "w" sound, resulting in the pronunciation and spelling variation we see today.
