 We noted earlier that language is potentially ambiguous at all levels of syntactic structure, and the same is true of semantic content, even for syntactically unambiguous words, phrases and sentences. For example, words like bank, recover, and cool have multiple meanings even as members of the same lexical category; nominal compounds such as ice bucket, ice sculpture, olive oil, or baby oil  leave unspecified the underlying relation between the nominals (such as constituency or purpose). At the sentential level, even for a determinate parse there may be quantifier scope ambiguities (“Every man admires a certain woman”—Rosa Parks vs. his mother); and habitual and generic sentences often involve temporal/atemporal ambiguities (“Racehorses are (often) skittish”), among others.
