Correct spelling for the English word "Spitfuls" is [spˈɪtfə͡lz], [spˈɪtfəlz], [s_p_ˈɪ_t_f_əl_z] (IPA phonetic alphabet).
I apologize, but "Spitfuls" does not appear to be a recognized or commonly used word in the English language. It might be a typo or a rare word that is not widely known or documented. Therefore, no standard dictionary definition can be provided for it.
If you can provide any additional context or details about the word, I would be happy to assist you further.
