This phonological collapse has led to a corresponding increase in the number of homophones. As an example, the small Langenscheidt Pocket Chinese Dictionary lists six words that are commonly pronounced as "shí" (tone 2): 'ten'; / 'real, actual'; / 'know (a person), recognize'; 'stone'; / 'time'; 'food, eat'. These were all pronounced differently in Early Middle Chinese; in William H. Baxter's transcription they were , , , , and respectively. They are still pronounced differently in today's Cantonese; in Jyutping they are "sap9", "sat9", "sik7", "sek9", "si4", "sik9". In modern spoken Mandarin, however, tremendous ambiguity would result if all of these words could be used as-is; Yuen Ren Chao's modern poem Lion-Eating Poet in the Stone Den exploits this, consisting of 92 characters all pronounced "shi". As such, most of these words have been replaced (in speech, if not in writing) with a longer, less-ambiguous compound. Only the first one, 'ten', normally appears as such when spoken; the rest are normally replaced with, respectively, "shíjì" / (lit. 'actual-connection'); "rènshi" / (lit. 'recognize-know'); "shítou" / (lit. 'stone-head'); "shíjiān" / (lit. 'time-interval'); "shíwù" (lit. 'food-thing'). In each case, the homophone was disambiguated by adding another morpheme, typically either a synonym or a generic word of some sort (for example, 'head', 'thing'), the purpose of which is simply to indicate which of the possible meanings of the other, homophonic syllable should be selected.
