The word "fenley" is not a commonly known word, and as such, it is difficult to provide a definitive spelling. However, based on the IPA phonetic transcription, the spelling of the word could be either "fɛnli" or "fɛnliː". The first transcription denotes the stress on the first syllable, while the second one indicates a long vowel in the second syllable. Without more context, it is impossible to give a more accurate spelling.
