This exercise -- that word isn't loaded -- highlights one of the parameters of haiku practice: when is a noun an image? Firefly may be an "image" depending on your background. Contemporary Haiku -- especially in US with our objectivist culture -- alone among literary forms ASSUMES that nouns are images; most literary forms assume that an image is a conjunction of words, nouns, adjectives, etc. The history of modern poetry is all about image, and the issues raised by Pound in theory and practice are still alive (see discussions of the poetry of Geoffrey Hill, for example). Perhaps the second word in this new form of haiku will provide that qualification, give the first noun, or "name," some texture and lived reality. Perhaps that's all that will happen in this form. (A discussion of the gap as "cut" will run into difficulties because of the weakness of the noun-as-image experience. The cut as understood traditionally is no mere pause; there is a great discussion of pause in the Penguin Classics Li Po Tu Fu volume ed by Cooper). But in terms of an exercise "generating" some texture through contexture-- by being related to another word -- well, no harm done if one realizes that what this is all about is overcoming the LACK of felt meaning in the noun itself (as opposed to the noun in a given culture, which may not be something a writer, qua writer (qua mindful communicator) should count on.
