"Winklehawk" does not appear to be a commonly used word, and it is not found in most dictionaries. However, if we break down the spelling using IPA phonetic transcription, we can get a better understanding of how to pronounce it. "Winkle" would be [ˈwɪŋkəl], and "hawk" would be [hɔk]. Putting them together, we get [ˈwɪŋkəlhɔk]. This spelling seems to be highly unconventional, and it is unclear what the word is supposed to mean. Without further context, it is difficult to determine how to use the word in a sentence.
