Identify the incorrect word in this sentence: You should try on many another pair of shoes before you decide which ones you want to buy.

The word "another" is incorrectly used in the sentence. The phrase "many another" is not grammatically correct; instead, "many other" should be used. "Another" is singular, referring to one additional item, while "many" indicates multiple items, which requires a word that can accommodate a plural reference. The correct phrasing would be "You should try on many other pairs of shoes before you decide which ones you want to buy." This adjustment maintains proper agreement between the quantifier "many" and the noun phrase "other pairs."
